Trying to get a 3.108 finish boreI am not gifted with boring out small engines but I dont see that idea working. I think it will get really hot too. Could possibly work if you put a bunch more of support on motor but I still think you went way to big. What will bore be when you sleeve it?
Looks like a little bit too much overbored, idk if the make aftermarket replacement pistons over 0.3" overbore, im not an expert but that's what I sawMaybe tried to go alittle big on this one! Hahah hopefully will still work with a thick sleeve! What do you guys think?
