joe schmo Posted July 21, 2014 Report Posted July 21, 2014 I'm taking apart this motor I have no problems with to replace old gaskets and seals etc. I have 2 different pistons in it I think Yamaha (225) and wiseco(2.25 513p9 cd 19910) ,same bore size but different porting.... can I run them again with no problem? Idk why I can't upload any pic's!!! Quote
BUILDER Posted July 21, 2014 Report Posted July 21, 2014 If it has 2 different size pistons in the the weight is going to be different and that is not a good idea to do that! Quote
Starwriter Posted July 22, 2014 Report Posted July 22, 2014 same bore size but different porting.... can I run them again with no problem? WTF??? 1 cast piston, 1 forged piston, different porting? Quote
m671054 Posted July 22, 2014 Report Posted July 22, 2014 He probably means intake windows. And no buy 2 new pistons 1 Quote
