Hi guys i got the 2000 R6 with 100 000km on the clock i always made sure the oil was changed and the right amount. But one very sad day something went wrong, i lost alot of power while doing only 158kmh with white smoke coming out and you know what that means. got home pulled the motor out only to find a large part of the sleeve is missing and it´s nowhere to be found even the valves look good and the top of the piston . please if some one could tell me what happened so i know the next time how to fix it thanks
