I have rebuilt many 2t's and they always smoke like crazy after a fresh rebuild but maybe that's because I soak a rag in cheap 2t oil and wipe everything down to get a thin film before I assemble it.
Not sure what kind of race oil you are running but I would be freaking out if my fresh rebuild wasn't smoking.
@Spywell Amzoil Dominator. But thats it, I dont soak everything down. Using my finger I put a film on the small end, wrist pin, cylinder bore and piston, and run some extra on the rings for reassembly, then pour some around the big end bearing, thrust washers, and down the holes for the main bearings. It's just how I do it, and I've never gotten a lot of smoke out of it. The way I look at it is after the first few revs it's getting lubricated by the oil in the fuel and the excess is washed away
@rustyATV Amsoil isn't a smokey oil, I have also heard that you should break in a cylinder using a cheaper oil because amsoil and klotz R50 or Techniplate protect so much that it's hard to get a good break in. I usually break my quads in with Yamalube R2 then switch to a Klotz oil, especially for the dunes on a 63hp 2t. Just stay away from the gummy cheaper castor 2t oils.
@Spywell Amzoil will smoke plenty when used in excess or when overly rich. It will also ooze a lot when rich, too, as I've found while slowly getting the YZ250 dialed in. There are countless variations on wearing in motors, this one works fine for me, others may prefer something different.
@69CRUZR If you could have seen what went into trying to put the motor together with the Wiseco crank (I should be clear, Wiseco CRANKS, their connecting rods are fine) you wouldn't go near them; the fit was atrocious. I've also seen many other complaints about their cranks' quality and fit both on Youtube and forums. Personally, I think the OEM crank is the way to go.
@mXfAcToRy787 Well, that confirms a couple of suspicions. No, It's just a douche like you is a dime a dozen and I long ago grew tired of repeating myself to the same foolish posts with the same foolish attitude. Feel free, though, to continue visiting my videos and upping the views. Just realize that you'll be talking to yourself should you choose to post, from here on out.
@rustyATV i'll agree with mX... You might wanna learn alil about 2smokes before you talk on youtube. it shouldn't be that damn hard to start on a fresh build. normally only takes 3-5 kicks for a 2stroke to crank on a new build. also it SHOULD smoke no matter what. When a 2stroke DOESN"T smoke then ya got problems dude
@kingman14 Turn your idle screw a few turns out and see how well your bike starts. That's what happened here; I had turned it out before I put the carb on to bring it more towards the mid range of the adjustment, hence why it started when I held the throttle open, but wouldn't idle without my hand on it. Also, the motor is still running on this rebuild, same jetting I had raced many years with, and same jetting I have now. Don't you think it would have shown up by now if it were a problem?
@thedarkestnight100 Yes, it's a Paul Turner Type 6, but the silencer is a Pro Circuit. One day, when I do my port trick from my other video I'll try to use a Paul Turner 2003 Race pipe and see if I can get away with that.
@uae3276 The break-in procedure is often described in terms of "heat cycles", which is the process of starting the engine, bringing it to running temperature, then shutting it off and allowing it to cool to air temperature before repeating. Opinions vary widely, but generally you'll want to do a minimum of three heat cycles when you assemble a fresh or new engine. More heat cycles is considered safer and machinists will set piston/bore tolerances closer if they know the user will do so.
@rustyATV thanks, but does this also apply to 4 strokes since i just finished rebuilding mine and put a big bore kit on it, so when i start it it idles fine so im not sure what you mean by running temperature, do you mean when it is warmed up, since my quad gets warm straight away, most probably because i live where it is 25 degrees celcius atm. so i start it, let it run for 5 min(idle??) then shut if off and wait till its cooled down...repeat...
@uae3276 Yes, this applies to four strokes as well. Here is a link to a tech document about it (replace the (dot)s with a (.) This leans on the safe side of break in, but is good practice. duncanracing(dot)com/TechCenter/atv_breakin4strk.pdf
What's happening during break in is you're letting the engine wear down marks and small metal burrs left on the parts when they're made. The parts generate more heat than normal during this time, so the engine runs hotter than it's designed to.
NICE 250R BRO.....SOMETIMES THERE JUST COLD NATURED...BUT MAYBE IT WAS FLOOODED...AFTER A FRESH REBUILD I AT TIMES TURN OR LEAN THE BIKE OVER UNTIL IT SHOOTS A LIL GAS OUT THE OVERFLOW...WORKS WONDERS FOR HIGH COMP
those honda 250r's and the suzuki lt250r's are soo much damn dun. i use to have a lt250r but it got stolen a few weeks ago. and my buddy has a honda 250r.. but mine had more more work done to it thus making it much quicker.
@canadiankid621 I haven't tried to find out recently, but I used to assume 12 miles per gallon when I raced hare scrambles. That's at race pace, though, and before I really tuned it right. They'll do a little bit better than that.
goddamnit i want one so bad, its so annoying trying to find one in good shape in southflorida, and then when u do find a good clean one the owner wants 4k. -__________-
@d00mofhumanity Yeah, tell me about it. When I got mine back in '99 I had to drive from Atlanta up to Portsmouth, Va because it was the closest one I could find for sale. Now there are a few that look decent for under $2000, though a couple of dreamer wanting $3000+ for a hooptie.
@rustyATV Im trying to build a yz250 or if i come across a yz 490 im tryna swap either into the blaster right now and id trade it all away for a trx in ANY condition LOL
When refreshing an engine, yes I use plenty of oil... I oil the rings, piston, cylinder walls, wrist pin and bearing. Never once has this given me a problem. I guess you enjoy trying to teach a few people some basic stuff on here, but all they need to do to learn more than you offer or know is get on macdizzy.com
I have a brother-in-law that sounds real similar to you, he is from WI. Knows what he reads and that's about it... I promise you don't know anything more than me about a trx250r.....
@gwkchevy Wow. So abrasive. Funny you mention macdizzy.com; I used to moderate on there years ago when Rick ran it as a free site. My friend DeoVindice moderated on there for a while as well. Try again with your Dr.Phil impersonation; only half of my 250R and two stroke knowledge comes reading, the rest is from the 11 years I've built, tuned, and raced a 250R and now a YZ250, doing everything but pressing cranks and rebuilding shocks. None of my pistons come out burnt, stuck, or otherwise.
@rustyATV really don't care.... deovindice, mexican i guess? How did you know I was dr. phil? Also, look at my arens frame and see that it uses the stock brake rear lever. Didn't have to take it off. yes you are right your videos are for the beginner. enjoy your teaching. your cylinder cracked huh, thought you had no problems.....
@gwkchevy Dont care all of a sudden? Sounds like backpedaling. If you look closer at the video I didn't have the stock brake pedal. I only spend a minute explaining that. But I understand blind anger affects reasoning. And being such a 250R expert Im sure you already knew that the early cylinders are weaker and the later ones have casting changes in the area that cracked to address that issue. DeoVindice Mexican? You're showing yourself to be such a sad stereotypical American; angry and ignorant
@gwkchevy ....... Deo Vindice is Latin for God is our Vindicator. I also happen to be a Civil War Re-enactor, a home gunsmith, and a competitive shooter capable of repetitively shooting a 12x12" gong at 900 yards.
Also, if you knew as much about TRX's as you note that you do, you would know that the 1986 cylinders are more brittle and tend to crack when you do serious portwork. Why do you think that Pro-X added those reenforces to the reed cage area.....they do afterall have similarities.
@gwkchevy............. LOL, I am STILL a moderator on there, and I port two strokes from GA to AZ. I guarantee you that we both probably know more about a TRX250R than you do. rustyATV is merely giving easy vids for the newbies coming into the two stroke world. BTW, I am good enought at tuning that I tuned a TRX OVER THE PHONE for a TRX in AZ. Merely by sound. It has been ridden by many people and even was sold and listed on Craigslist as being the best running TRX the seller had ridden.
Yea because a cold engine requires more fuel than a warm one. more fuel means more oil which means more smoke. The more a bike loads up and runs with lesser rpms means more oil builds up. after running it hard the oil is burned out of the cylinder and into the exhaust.
@gwkchevy Thats partly true. Unburnt vaporized fuel and atomized oil are flowing all around a two stroke engine when its running, however when shut off and allowed to cool, this settles and pools in the bottom of the crankcase. This pool sits until the engine starts running again (the choke is to GET the engine running) at which point it is agitated and picked up by the engine and burned. It's not metered by the carb, however, just by the movement of the engine, so lots of it gets thrown
@gwkchevy into the engine and causes the plume of smoke until it is cleared out by a few blips of the throttle. When you disassemble the engine and clean it, however, this pool of fuel and oil is not there (unless you use an excessive amount of oil on assembly), so when you start it cold then, you don't have this unmetered quantity of fuel and oil throw into the engine and, if you are jetted close to optimal, you won't get any real plume of smoke when you start it for the first time.
If you mixed your oil in your gas, it will smoke.... I don't care how fresh it is, it will smoke. When you put the cylinder on you should use your 2-stroke oil to lube the cylinder, piston, and bearings... Should smoke more than usual after a fresh re-build... Is it a cast iron sleeve? Is it 265cc? what reeds/ cage?
@gwkchevy Whoops! Typo. I meant to ask if you knew WHY two strokes put out a plume of smoke when they're started cold (not after a rebuild), but then none when they warm up.
Thats what mine does it wants to start but it wont you can never tell when you almost have it running it starts when it wants to and when it does.B-B-BEAST!
@arcchris I'd like to see you kick start a quad when the carb is maladjusted. But if you think I've got pansy legs, meet me at the gym and see if you can squat more than I can at 270lbs + bar.
@arcchris Again, with a maladjusted carb. The only reason it started when it did is because I held the throttle open. And 270+bar, granted not the most out there, is a lot more than most guys care to do. There are guys at my gym who bench that but won't squat it.
@dlinecg This was brought on when I cracked my old cylinder. Was hoping it would just be a cylinder swap, but then I found the crank needed servicing (actually, replacement), and then found some damaged parts in the transmission. Eventually I got it back together with the Duncan Powervalve cylinder on it. The new cylinder is set up as a true 265cc motor. Power? Tough to say, but with a low end woods pipe and my 210lb butt, it will give piped LTR450's a run for their money.
@dlinecg No, I believe that's the serial number and it works out to mean number 67 of the the 2000 cylinder. Go to the end of my "Stripped Head Stud" video. The serial number on mine is 22071, which is the 71st cylinder of the 2002 cylinder. If I recall, the 2000 cylinder had an iron liner.
I'm a bit over 6'2". The R sits me a bit on the low side. I've lowered the footpegs as much as I can but because the seat is so low, it can be tough to get up in long races. Also adding a +1 steering stem and the right set of handlebars helped keep me from bending over too far.
Grow a pair of balls and kick that thing hahaha seriously i could've started that thing in like 2 kicks. I tore down and rebuilt a motor in about 3 hours tear down and build up isnt fucking rocket science...
All the balls in the world won't do you any good when the carb isn't set right. It did in here only when I held the throttle open. It starts on the first kick, now. And it's not like I'm a wimpy kicker; I used to start hare scrambles with my butt on the seat.
Yeah, I got lucky with that one. Traded my old beat up Type 6 for a 2003 Race pipe, and got this Type 6 for pretty cheap. I've been toying with the idea, though, of getting an OEM 250R pipe and cleaning it up, as I hear they're a good blend between those two pipes in terms of power and smoothness.
not trying to be a dick or anything but do ya think you really had to take the break lever off. haha just kick it. great video, great machine, and nice work rebuilding
Since it turned out the idle setting was too low, maybe not, but the brake lever was keeping me from getting a full kick and the catching the kick lever. I have the OEM TRX lever on there now; haven't tried putting the CR250 lever back on yet.
Yeah, it did. Guess it doesn't seat as easily when it's all clean.
What was wrong here was I had adjusted the idle stop screw out because I thought it was too far in; the engine fired when I gave it a little throttle and I had to hold it to keep it running. You can see it dies without me hitting anything. I've been messing around with the idle stop and air screw since then.
Ouch. When I put this one together, I found a lock washer from a different motor on the table and panicked a bit.
haha yeah i know what ya mean, every time i see a bolt or a washer of some sort on the ground i start to panic to lol :) then im to scared to start the engine till i get over it.
you said it wouldnt smoke after being rebuilt. i had my R motor rebuilt, new crank,new topend etc.. and it smoked the first time i started it. what does that mean?
i had a very well known builder in my area rebuild mine. i remember him saying that he oiled it real good! i trust his work, but i was just being curious.
There's nothing wrong with that, good to be a little slick when everything's new. The smoking from regular running is just fuel/oil that didn't get burnt when the motor was shut off and settled in the bottom of the crank case and is stirred up when the engine's started again, basically causing the engine to run very rich for a brief period.
oooooh... my shin hurts just thinkin about it. ;) I've got a 'permanent shin guard' attached to my shinbone now thanks to my R. Machine looks pretty good, sounds tight too. ...and I'm subscribin' . Right on Bro!
They never start right up after a fresh rebuild, you gotta get that gas flowin in there, they always take a shitload of kicks till things "break in". Plus its gotta be tough getting a good solid kick in sneakers :) Sound good tho. Protect those shins !!
ps, check out my video's, I have some videos of my R's. Ones a red '89 with Roll and Axis suspension, the other is a completely custom LRD framed 300PV.
I subbed to you BTW, I like your videos, you seem like a good guy.
Every time I've put a motor together it's started within a few kicks, but I normally have the same setup as before. This one is totally different with the new cylinder.
Marc, you are a brave man for kick starting Junior without your boots on! I have felt your pain before with my Ole Girl! YAY, you be running again!!!! Can't wait for your break-in, and your ride, and comparison of the PV vs. the non-PV'd cylinder.
What's with that tank lol.

@arcchris I'd like to see you kick start a quad when the carb is maladjusted. But if you think I've got pansy legs, meet me at the gym and see if you can squat more than I can at 270lbs + bar.
rustyATV 1 year ago
@rustyATV lol its honestly not that hard, i have a CR250R i just rebuilt, kicked once n went. n 270+bar isnt much bro
arcchris 1 year ago
@arcchris Again, with a maladjusted carb. The only reason it started when it did is because I held the throttle open. And 270+bar, granted not the most out there, is a lot more than most guys care to do. There are guys at my gym who bench that but won't squat it.

what did the rebuild consist of? did you bore or stroke it or is it still a 250
about how much horsepower does it make now compared to stock?
dlinecg 1 year ago
@dlinecg This was brought on when I cracked my old cylinder. Was hoping it would just be a cylinder swap, but then I found the crank needed servicing (actually, replacement), and then found some damaged parts in the transmission. Eventually I got it back together with the Duncan Powervalve cylinder on it. The new cylinder is set up as a true 265cc motor. Power? Tough to say, but with a low end woods pipe and my 210lb butt, it will give piped LTR450's a run for their money.

@rustyATV im putting in an esr310 top end kit right now. where will that put me horespower wise? paul turner pipe, 39mm carb

@rustyATV wat is the bore size for a 265? is it 67mm?
dlinecg 1 year ago
@dlinecg It's at 68.5mm

@dlinecg
does this nimber "20067"
refer to a 67 mm bore? it is stamped on my friends pc2000 cylinder and he isnt sure what displacement it is. he just got the bike.
dlinecg 1 year ago
@dlinecg No, I believe that's the serial number and it works out to mean number 67 of the the 2000 cylinder. Go to the end of my "Stripped Head Stud" video. The serial number on mine is 22071, which is the 71st cylinder of the 2002 cylinder. If I recall, the 2000 cylinder had an iron liner.
rustyATV 1 year ago
@rustyATV alright, i lied about the esr 330. i ended up going with the pc2000 265 cylinder. just got it back together, hoping ill b satisfied
i already like the powerband, its very impressive because of the powervalve

Bought it. They are from FullBore. Much nicer than the Maier I used to have.

how tall are you? lol I only ask because I'm 6'4 and might get a 250r and wanted to know if it would be to small when I sit down.
theds650kid 1 year ago
I'm a bit over 6'2". The R sits me a bit on the low side. I've lowered the footpegs as much as I can but because the seat is so low, it can be tough to get up in long races. Also adding a +1 steering stem and the right set of handlebars helped keep me from bending over too far.

Nice bike, it's nice to see an old 250r get a fresh start. btw how hard he was kicking was not the reason it wasn't starting.

Grow a pair of balls and kick that thing hahaha seriously i could've started that thing in like 2 kicks. I tore down and rebuilt a motor in about 3 hours tear down and build up isnt fucking rocket science...
badtyman 2 years ago
All the balls in the world won't do you any good when the carb isn't set right. It did in here only when I held the throttle open. It starts on the first kick, now. And it's not like I'm a wimpy kicker; I used to start hare scrambles with my butt on the seat.

tankcenashow 2 years ago
Yeah, I got lucky with that one. Traded my old beat up Type 6 for a 2003 Race pipe, and got this Type 6 for pretty cheap. I've been toying with the idea, though, of getting an OEM 250R pipe and cleaning it up, as I hear they're a good blend between those two pipes in terms of power and smoothness.

not trying to be a dick or anything but do ya think you really had to take the break lever off. haha just kick it. great video, great machine, and nice work rebuilding
boosh199 2 years ago
Since it turned out the idle setting was too low, maybe not, but the brake lever was keeping me from getting a full kick and the catching the kick lever. I have the OEM TRX lever on there now; haven't tried putting the CR250 lever back on yet.

02:24 - was that the kicker i heard skip?
fresh engines need that little bit more fuel in the cylinder before start-up(pre-load).
when i went for the first ride on my freshly built 426 the damn clutch basket came loose lol
89Silhouette 2 years ago
Yeah, it did. Guess it doesn't seat as easily when it's all clean.
What was wrong here was I had adjusted the idle stop screw out because I thought it was too far in; the engine fired when I gave it a little throttle and I had to hold it to keep it running. You can see it dies without me hitting anything. I've been messing around with the idle stop and air screw since then.
Ouch. When I put this one together, I found a lock washer from a different motor on the table and panicked a bit.
rustyATV 2 years ago
haha yeah i know what ya mean, every time i see a bolt or a washer of some sort on the ground i start to panic to lol :) then im to scared to start the engine till i get over it.

you said it wouldnt smoke after being rebuilt. i had my R motor rebuilt, new crank,new topend etc.. and it smoked the first time i started it. what does that mean?
hondatrx450rguy 2 years ago
How much oil did you use to assemble it with?
rustyATV 2 years ago
i had a very well known builder in my area rebuild mine. i remember him saying that he oiled it real good! i trust his work, but i was just being curious.
hondatrx450rguy 2 years ago
There's nothing wrong with that, good to be a little slick when everything's new. The smoking from regular running is just fuel/oil that didn't get burnt when the motor was shut off and settled in the bottom of the crank case and is stirred up when the engine's started again, basically causing the engine to run very rich for a brief period.

oooooh... my shin hurts just thinkin about it. ;) I've got a 'permanent shin guard' attached to my shinbone now thanks to my R. Machine looks pretty good, sounds tight too. ...and I'm subscribin' . Right on Bro!
MIKECRAIGEN 2 years ago
They never start right up after a fresh rebuild, you gotta get that gas flowin in there, they always take a shitload of kicks till things "break in". Plus its gotta be tough getting a good solid kick in sneakers :) Sound good tho. Protect those shins !!
ps, check out my video's, I have some videos of my R's. Ones a red '89 with Roll and Axis suspension, the other is a completely custom LRD framed 300PV.
I subbed to you BTW, I like your videos, you seem like a good guy.
RustyCyler 2 years ago
Every time I've put a motor together it's started within a few kicks, but I normally have the same setup as before. This one is totally different with the new cylinder.
Sounds like a sweet quad! I'll check it out!

Marc, you are a brave man for kick starting Junior without your boots on! I have felt your pain before with my Ole Girl! YAY, you be running again!!!! Can't wait for your break-in, and your ride, and comparison of the PV vs. the non-PV'd cylinder.
PS. Thanks for the Porting Plug-in, BTW! ;^)
