[QUOTE="Mark Johnson, post: 1474733, member: 145603"] I think I'm in the same boat. New to this site. New to dirtbikes and 2 strokes. Bought it used. Ran it hard for about 2 hours and it died. compression measured at 80 psi, so I installed a new .5 mm oversized piston. compression at 120 psi. It won't start! I tried the idea shared to crank it over upside down to drain the gas. I was able to get it to run, but only for a short time. I think previous owner stated he installed a larger jet in the carb. Could this be the problem? What size jet should I be running? [/QUOTE]
