[AllEyezOnDenIli]

i need the bottom end vid , daaaamn, i was so happy to find this vids and just the one i needed is blocked by EMI ???

[travi3so67]

11:39 you have your piston in upsidedown

[alexsuchapimp]

@travi3so67 wow you're an idiot

[destruction12100]

your supposed to have a tube coming out of the little hole in the ohv cover so dirt doesnt get in it.

[thebobssat]

On the gx200, if you put the gx160 head, you will have more power because of increased compression.

[PaulyStax]

all your captions are past tense, lol. motor is cool

[Learnthethingsido]

Nice job kid!

[mudpuppy4life]

where did you get your intake at?

[stevieb2012]

Wow real nice vid man! Finally got to see how the whole set up works helped a lot cause I'm working on my own GX200! Good job and sweet engine!

[Hogasofa]

does that carb make a difference from the original one please reply.

[XxMusclecarsxX]

nice engine!! :O

[rca75415]

now that you have changed almost everything on engine,what is her compression (in lbs.) now? the stroke lenght (in inch),dia.of the piston and RPM?

[cg5]

whyy do you need music? makes the tutorial crap

[91redneckproductions]

was it bored out at all u milled the head but what about over sized piston?????

[BurtonAir161]

That motor looks friggin sweet!!! The only thing I would suggest you change is this. Take off that briggs muffler at the end of the high flow pipe and put on an RLV silencer. That should help your torque curve and make it kick off the corners a little quicker then the briggs muffler. Other than that the motor should be VERY fast!!

[rogerkart]

Hi i have bought a semi tuned gx200 and want to put a 22mm card like yours on with that exhuat of yours as well how did you get the piece on the inlet side so you can use it as a slide on and can you tell me where to get exhaust.awsome engine.

[breamachine]

Hello, I have a gx200 with ali flywheel, high lift cam, agk air fliter and bored out gx200 carb, with c -pice exhaust. what hp is that?

[banksstinger]

i can anwser that question, you will have approximately 153 hp! good job! you offically have the fastest mini bike in the world!!

[Natemanperson5]

@banksstinger complete bullshit.

[matthewmarrs123]

i busted my knuckles trying to change the oil on a baja mini bike when you barely have space to move your hands...tore 3 fingures up and ripped a knuckle...

[manout234]

baja minibikes are 300 doller peices pf shit

[troy5251]

it doesn't matter if its at TDC carharttFbco the flywheel will only go on one way

[JasonMann8]

nice

[carharttFbco]

wow, pretty sure the piston isnt in the right way, and you shuda had your engine at TDC when putting the flywheel on,

[boaterbil]

Why the He-- Would it matter if the piston is at TDC? it's keyed!

[Dragracer5100]

Looks like someone used a chisel to deck that head. Who machined it?

[gx200honda]

what rocker arms are you running? i have basically same set up as you and im running standard rockers. we think they keep bending under high rpm and causing the exhaust valve to keep breaking.

[larsbuller]

are you using 18cc head or 14cc, I nealy the same engine like yours, only different is gx390 carb

[C411M3]

14cc head

[sonayvaio]

@C411M3 hi i have chinese engine on my cart which looks same as this engine even spare parts are the same only problem is when i starts the engine caught up speed and carb is not fuctioning properly as they told me the buterfly inside i snot closeing so its intaking air inside , how and form wher ei can can get a carb with new air filter so i can fix my cart , your reply will be very helpfull , nice video thanks

[racorbitt]

Can't stand it due to the music

[boaterbil]

I agree c411bitt. Why have music (which I find annoying) on a demo video.

[wcsnoman]

How much did it cost you, in upgrades would you say?? Im looking into doing some hp ugrades for my gx200 clone

[gx200honda]

what rpm do you get from that thing? i get 8400 outa mine :D

[C411M3]

mine is geared up for 6000rpm, havent taken it over that.

[gx200honda]

why have you only geared it to 6000? ive geared mine to 7500 and you should get more rpm than me with that motor. im still running the standard flywheel that you used to and mine is fine. so you didnt need to change if your only doing 6000 with it.

[Briggsmaster]

wat website did u get all the parts on

[C411M3]

agk and nr racing

[jozay70]

forgot to put 308 cam

[jozay70]

now next thing u need to do is put 1.2 roller rockers and 308 with some clearence and go with 348hl alky tlil. carb

[jozay70]

think u need to put a billet flywheel

[C411M3]

arc billet flywhells is now installed

[mudpuppy4life]

i want to see the kart and here it

[C411M3]

give me a couple of weeks and ill get it out of the garage and fire it up for u

[C411M3]

vid of kart on now running!

[gx200honda]

good choice in cam. that engine should be rapid!

i have done same as you accept aint done mikuni or bliger valves. mine will rev to 8400 so fuck knows what yours will do. good luck using that standard flywheel! lol btw you should cut every other blade off of the flywheel fan to get it to spin quicker.

can you put a vid up of it running please.

check my vids,

[C411M3]

billet flywheel now installed, vid of engine running posted also.

[Hogasofa]

@gx200honda but you don't want to cut off the blades right or else it will over heat won't it?

[gx200honda]

@Hogasofa cut every other blade off and there fine, it makes less drag that is the general idea

[minidragbike]

Hey know need to get all upset. If you need helpful info just send me a message. I can also tell ou what all is inside of my motor. You don't have to guess.

[pilgor87]

That flywheel is going to kill you

[donaldrox]

yea yea yea it is a fucken proven fact that if you have a big valve head with a .290 lift cam you will produce 20hp oh yea you also have to have a bigger carb and i know that he has a 276 lift cam which with the stock rockers will come out to be like .28? proven fact! he also has a high flow exaust + 18lbs valve springs i know maby no 18hp but at least 15hp+ which i think is still a good combonation ohhh almost forgot the parts were pre lubed he said in a reply bc they came off a nother engine

[technineriderTEH]

hey dude, can you message me, i fucked with mine (its a honda clone) same stock parts as yours. Im trying to remove the rev limiter (push the pin through the block) but i cant get teh flywheel off, anyway what my real problem is that i fucked up the valve timing when I pulled of the case cover. how do i adjust them? the timings pretty close to stock, but theyre not quite. help me please

[donaldrox]

look up "honda clone" moter govner removal it works with the honda gx200 too

[minidragbike]

He should have between 12:1-13:1 static compression depending on how much it's milled. I looks to only be milled a small amount. Maybe no more than 0.040"

[minidragbike]

Your combo of parts are wrong. But you should still make about 14hp.

[donaldrox]

how is the combonation wrong i bet you are just one of those kids who think they know every thing but the really dont know shit

[minidragbike]

I know plenty

The carb is way to small. That's the carb size you run with a stock valve head. I'm also the guy who design the .276" cam he is gonna run in this video. If he changed the carb to a tillotson 1" bore, or a 26mm mikuni he will make about 2 more HP. Check out my videos, and look for my GX200 motor. Running!

[justin5666123]

bitch i wanted to hear it run

[C411M3]

i will do a video of it running soon

[pilgor87]

did the flywheel come with magnets on the inside to run a magneto?

[clonedoctor]

byw, what is your actual compression ratio on this engine?

[C411M3]

12:1 plus whatever the flat top piston and thin gasket add to that.

[clonedoctor]

hey, 224736, flatheads don't make as much power with the same displacement cuz their compression ratio is limited to 7:1 cuz they dont have an overhead valve design.This guy probably has about a 14:1 compression ratio cuz of the 200cc displacement and the 14cc head i'm guessing. dont be such a jerk about it

[C411M3]

clonedoctor is 100% correct 224736

[yelson910]

there was 2 much milled of so the valves started touching the piston and it all went bang and seized up so now we r not big fans of agk! just out of curiosity where abouts r u do u live in england? cause as uve done all this tuning be4 u would be a gr8 help!

[224736]

if tahst what ya rekon a engine does not stay that low of rpm and have that much hp idiot pretty sure me mate who is a go kart pro did his briggs up to 9hp from 7.5 and it was pullin 11,000 rpm and he blew a crankshaft a billet rod and his hybusa valve springs in one month and ur gonna sit there and tell me a chinese fuken engine is gonna perform better and stronger then a brigsg and stratton engine no ur not

[C411M3]

oh, go away you silly little aussie school boy!

[C411M3]

you havent even watched the video have you. you havent got a clue what your on about. engine is good for 8000rpm + and been dynoed at 17.6hp.

[yr12005]

8000 rpm with a stock flywheel, The shit is real deep over here......

[yelson910]

gr8 vid ive got a gx 160 and have done a lot to it i got the parts from affordable gokarts but they sold me a milled head and it wrecked my engine so now onto the spare! i have got a lot of power and i race my brothers 200 and its really even but can u give me advise on anything else thanks dan

[C411M3]

strange! my head has been fine, what went wrong?

[Lionspirit08]

or find this engine is possible let me know cheap price

[Lionspirit08]

hey does a gx200 carb fits a gx160 and works? and wonder where to get 1 let me know ok ill reply here in awhile or so

[C411M3]

gx200 carb will fit gx160 perfect. exterier is the same. only difference is gx200 has bigger internal flow hole, hence more fuel in = more power.
