Honda TB 88 with RH Installation Part 2

[HMFboy29]

hey me again got my z50 running and if you slowly pull the throttle it goes but if you go past certain point or do it fast then it bogs down

[djgeraghty88]

@HMFboy29 sounds like a jetting problem to me

[tamur1994]

2 ppl did it wrong

[konazzzz]

How much all that stuff costs? 

[larsge]

Those 88cc kits sound the business

[agropp1]

[Jgm73tube]

hey alex... where did you get the 88cc kit from? im looking to get one for my 1984 atc70. did the kit come with everything or did you need to get other parts else where? thanks...juan

I have a crf70 for my son and just got the 88cc bbk from Trail Bikes. Once install is complete whait is needed for first start? Is there break in sequence needed for the rings to seat correctly? I have heard different things- run 1/8 throttle for 10 min- then let cool for 30 min, run 1/4 throttle for 5, let cool and then good to go. Is that good? What do you suggest?

Thanks for posting the video! I never understood why the copper washer went on the bottome left stud. I do now.

[TheAlexManVideos]

I just ride the bike easy on some trails or somewhere that it won't get revved up or really hot for 30 minutes or so then give it hell. There are so many different methods that are "the best way." Just do what makes you feel good.

Sorry I dont know how to post a comment on youtube yet. This is for TheAlexMan. First, thanks for the instructions. They made the work easy. I am not sure on what to do about one thing. There is a vent/vacuum tube that comes off the small box on the frame that went to the old carb/air filter. What did you do with that? I didnt see anywhere to attach it on the new carb.

[dirtti]

Very nice video! What carburator are you using?

[TheAlexManVideos]

It's the one that comes with the kit. It's a Shengwey 20mm which is a knock off of a Keihin 20mm.

[chi22to]

thanks friend your video is excellent greetings from peru

[pax502]

thats cool

[yousuck669]

why would u sink money into that old thing

[mrkmotocross]

why not?

[seb182c]

and this kit can go on a honda trail 50 1983?

[TheAlexManVideos]

Yes.

[seb182c]

how much fast can you go after the mod?

[TheAlexManVideos]

Depending on gearing, should be able to hit 55 or 60 mph.

[XR50ryder]

Wait, are you saying with stock gearing i could go like 50?

[TheAlexManVideos]

If your motor revs high enough. I do not have stock gearing.

[seb182c]

ok thanks

[seb182c]

hello i want to have some information on this kind of engine who showed in the video , if someone have information of where we can buy it send me a message

[TheAlexManVideos]

It's a Z50R engine with a TB 88 RH kit on it. Motor can only be bought used. Check eBay.

[coshyno]

what kind of pipe is on that

[TheAlexManVideos]

Pro Circuit T-4 with the spark arrestor removed.

[cdoublejj]

aaaaaaaaaaahhhhhhhhhhh PM cam cover!!!

[TheAlexManVideos]

That's just a Honda cover. I painted it myself.

[jameslee522]

i have a 88kit in mine, i bought it that way. Well its tapping very loud at all rpms. If with the motor off if i move the rotor back and forth you can here it tap. Any thoughts as to what this might be? Ever seen rod bearings go out? i dont know what els it could be.

[TheAlexManVideos]

Adjust your valves. DO NOT RUN THE MOTOR UNTIL YOU HAVE DONE THIS!

[jameslee522]

valves were adjusted. That was the first thing i checked.  I dont know what els it could be other than rod bearings. Can you think of anything? If it helps in the high rpm range it boggs out.

[TheAlexManVideos]

Well, what else did you check so I'm not wasting my time telling you to do stuff you already did?

[jameslee522]

Thats the only thing i have checked. The only other thing i can think of is to check the timing. What i dont understand is with the motor off and set to tdc on the compression stroke. If i move the rotor back and forth it makes the clanking noise. I dont think it would be the valves as they dont move on the compression stroke. What are your thoughts? And thanks for the reply's!

[TheAlexManVideos]

Well, could be that the piston is contacting the head if the wrong parts were used. Check the cam timing. If that doesn't immediately tell you what's wrong I'd say it's time to pull the top end and inspect everything. The rod bearings don't really go bad with these motors, but I'm not saying it's not possible.

[jameslee522]

alright ill try that this weekend. Thanks

[jameslee522]

More info about it. xr 2001 bottom end with the takegawa 88 kit, PC18 Khenin carburetor. I see in the 88cc s-stage combo kit it doesnt come with a high volume oil pump. Could that cause it.

[wingking077]

you need to buy some gear dude, fools ride without gear

[mohalkcrazy7]

what mm is the carb i just put 85cc kit on my honda 50 and ppl said i nedda run a 70cc honda carb let me kno thanks

[TheAlexManVideos]

This carb is 20 mm. You can probably use either the carb off of a 70 (17mm), an 18mm, or a 20mm.

[mohalkcrazy7]

what would u recommend?? \?

[stlouissux9119]

[Despise01]

nice vids btw :)

[mtpratt32]

Is that a Honda bottom end or Chinese clone. If it is a Honda bottom end, what kind of Manual Clutch kit did you use? Love your videos. I have a 99 z50 that I want to build up into a backyard mxer. I'm putting xr/crf 70 front suspension with the xr75/80 rear and a decent shock that I haven't located yet. What do you think about the TB108 kits? Isn't that your kit with the stroker crank? Are you still running the stock 3 speed trans? Sorry for all the questions , I'm just a 50cc noobie.

[TheAlexManVideos]

1984 Z50R bottom end. ATC70 4 speed tranny. TB manual clutch with billet basket. 108 kit has a lot more torque. Yes it has a stroker crank but also a slightly different piston. Same bore but different deck height and pin height.

[Silvergreenelsinore]

Great video. I have several bikes I am restoring 2 '69 Z50AK1's, 2 SL70's (K1 and K2) 1 XL 70 and 1 XR 75KO. Keep up the great work.
