Is your cylinder messed up to the point that it can't just be bored oversize and new piston? I believe the liners are cast in place rather than pressed in, but your Yamaha dealer might give some thoughts on this. Good luck!
does anyone know what i should torque the cylinder head on a 2005 yamaha 50 fuel injected engine? I was thinking around 18 pounds? I dont have a shop manual.
Start an new thread of your own. your question has nothing to do with that post you added it to. do a forum search for manuals and spend the money it will save you tons of time and money in the long run
