just bought a new 1mm over wiesco piston and had my cylinder bored and honed by a reputable shop. my question is my rings are measuring at 12 and 16 thou for the gaps. In the Yamaha service manaul, it says the extreme limit is 12 thou? is there any fluctuations between the years? or is something wrong with my rings and i need new ones? could someone look up the limit for the 2000?
