So I had my motor rebuilt on my 850R 5 years ago by RSI in Portland Oregon and my #3 piston skirt has cracked somehow and now I've taken the motor out for repair..I found a guy named Jason near where I live that seems capable of handling the repair.. I did get 5 years of spirited driving out of my rebuild but still very disappointing as I was not prepared for such expense. I'm hoping I can use my forged rods and go back to OEM pistons..I don't know yet how much the block will need to be bored out. Jason informed me I may have to get another block if I am going to use stock pistons. I'd rather do that than buy more Weisco pistons that could fail again. Just thought I would share my dilemma. I will post more pics when the motor gets torn down.
