I don't know... I couldn't find one.

There are little round caps on the top of the engine on the front and back. Under those caps are the rockers and valve stems. The first step is to get the piston at the top on the COMPRESSION STROKE. Not the exhaust stroke. Its up to you to figure out if you have it right because there are no marks to tell you. Once you have the piston at the top on the compression stroke, you then grab the intake rocker and see if its loose a little bit. If it is, then its probably ok. If its not, that is your problem. You have to make it a wee bit loose. Not a lot, just a little bit. .001-.003 to be exact. Usually, you use a feeler gauge for this. Too tight and it won't start when cold and won't run right. Too loose and it will run ok, but just won't have all the power it could have.

 

but then that cant be it because it has been like 60-70 degrease and i let it sit in the sun and kick started it and the motor warmed up but it dint start easly and woudent idle or run for more then 5 seconds max

 

60-70 degrees is cold for an engine. A hot engine is one that you can't touch. 5 seconds is not enough to get it hot.

 

but after kick starting it and it starting up and ding a couple times the pipe starts to warm up and the motor starts to warm up because u are kicking it over.

 

hey randy.do you think it may be cosing this hole thing because the motor is not geting enof fuel?maby my carb is bad?.and if i do sell it as is how much do you think it is worth.?and if i dont sell it how much will a new motor be?

well iam not trying to sell it just yet.....i was asking because my nabors brother had offerd me a pockect bike that is wourt like 5-6 hundrad dollars.but i dont what i nother bike..but how much for a new motor

 

I didn't see anything on ebay. THe 250 engine will be HARD to find! A 230 engine will be easier. You have to keep looking until one pops up. Email some of the sellers that sell 230 stuff n ask if they have one.

 

well my nabors brother just bought a new motor for his..i think its called monster or gorila or somtiuhng like that.

 

.hey can i put i quad racer motor in my frame?
