Just checking if i have this right.Long straight at Pukekohe race track slowing for hairpin back wheel locks bike seized,not to bad as it strarted next kick but on dismantling bad damage to piston and barrel.Anyway,the piston crown is undamaged and has black deposits the spark plug is a ten range and is medium brown no detonation marks to be seen.So my thinking the bike is full race with jha jet kit could it be off throttle fueling maybe bigger pilot jet in conjunction with up a size main jets.(it was the right/front cylinder)what do you guys think?.
