yeah, just broke down yesterday lmfao. air cooled motor with ported top end, pvl ignition pipe, 28mm koso carb... not sure what all went, the carb float is jacked it was pooring out fuel, the clutch had a full slip problem, the motor is all jacked too lol. gotta check compression and open the clutch and try to fix the carb... glad I fixed the LT80 so at least the kid has something to ride for now.. I have another block with a 3mm stroker crank that had a 53 or 54mm top end but I want to go thru it and build it up. air cooled also.
