what was the bike doing in the first place that made it run "funny"?

to be fair its probably just carb related or you needed to do the valve clearance. you've made alot more problems now youve ripped it apart :P

Ok the whole story is the bike started running funny and i had to keep messing with the coke and in my mind i was thinking maybe its just dirty so i got some carb cleaner and it still did it so i took the carb off and the gasket was split so i got a new gasket made up and when i took the old one off alittle bit of it fell down in the intake and not knowing much i took it apart only the head to see if i could fish it out and i did and puting the head back on i started it and it leaked oil so the gasket on the head was messed up so i took the head back off made a new gasket and now im not real sure if the timing is on but i still dont see where i could of unsealed the rings but like i said im not real small motor smart lol

i know i know i should of left the paper in there and let it burn off now i know that but now im stock and this guy wants me to pay him to fix it when i just spent all the money buying it so imma kinda stock thanks again for all your help.....

okay first get the motor back, unless hes taken the barrel off it forget about the rings. sounds like your carburettor needed a proper clean and the valves needed doing.

2nd - measure the height of the barrel itself and the diameter of the bore. then you can work out what the actual capacity of the motor is.

3rd - get on ebay and buy a full rebuild kit for that capacity engine. they are about $15 total. your gasket probably didnt work on the head because they proper ones have a little seal impregnated on them so they dont leak everywhere.

4th - The carb. If you still have all the pieces make sure you take all of them out and blast it out with carb cleaner then hold the jets up to the light and make sure you can see through them perfectly. just shooting carb cleaner at the thing wont do a thing

also make sure the atomizer tube (the one in the middle of the carb) has the holes along its length. if you screw the main jet in all the way it crushes the tube and then the carb is useless. stupid design

5th - get a can of permatex gasket remover and spray it on the top of the barrel to get all the old gasket off (make sure you take off the pair of rubber o rings on top of the barrel before you do this too). the top of the barrel should be spotless with no bits of gasket left on it.

same with the bottom of the head. unless they are like new you wont get a gasket to seal on it.

6th - then you can use your new gasket set to bolt it all back together, set your timing, do your valve clearance (.1mm on the intake .15mm on the exhaust) and put in some new 10w40 wet clutch compatible motorbike oil and your all set

or should be

Send me a PM if you get stuck and i can send some photos. or if you get really up S creek with no paddle bring it over if your in nsw. I just finished doing a pair of them, they arent too hard at all and you can do a full on rebuild really cheap. everything is cheap for these motors. i was surprised at what your money can get compared to normal pocket bikes

good luck.

I hate when i get up S creek with no paddle sucks when you gotta paddle with your hand lol

Any ways i got the bike all back together (before i saw this post) started it ran alittle funny when i give it some gas the rpm stays up for along time before it comes down so now when i go to shift its not real good lol so im taking the carb apart like you said but i cant get the throttle cable out is there a trick?

seems like its not lecking anything yet but it may start so i will order the gasket set and when it gets here ill put it on and i think its a x12 110cc but still not sure i found this gasket set on ebay and it looks the same as my old gaskets Atv Quad Dirt Pit Bike Engine Motor Gasket Sets 110cc:eBay Motors (item 170292294324 end time Dec-01-09 21:18:04 PST)
the one that says 110cc Manual Engine with Upper Starter 152FMH is my motor i think looks just like it heres the link New Engines / Motors

Hey, could be worse .... instead of being up Schist Creek without a paddle, you could be up there without a BOAT .....

Glad to hear you have it running again.
