Ok my buddy gave me 2002 yz250f for a project. Started project by getting whole top end redone. Got new valves, and all that stuff. Perfect. Nope no compression. Tried all the techniques and all that TDC stuff. Nothing. Anyways now where I'm at is no compression to kick it over, yet we can bump the bike and it runs perfect(or so we thought) all day long. Don't die, don't bog, Anyways we thought it ran perfect when we loaded the bikes up we saw gas leaking fairly slow out a big bolt on bottom of carb. Any idea what this is? Also a good shake while gas line is on off some gas will leak. And again the compression at the kicker is weak. Very seldom do we get any and just bump the bitch. I am ready to get this baby going right. I been looking at cams and stuff would that be the way to go? Please help me, I cannot take the sanity of the insanity of not being able to brapp!!! Thank you for all the help I receive.
