Hi
Took the jug off the XR 500 & found a very nice alomst new weisco 12:1 piston(according to the part#) Can i run that on 93 octane?. As this was how it was run prior to taking it apart. I do see alot of play between the wrist pin & rod. .0025" - .0035" to be exact. By wiggling the piston it seems like a ton. THe wrist pin & the bore in the rod are galled up a bit . A new wrist pin would help but the rod will still be galled? Any advice? I was told by someone that swap out the piston for a 10.5 :1 so i can run pump gas without detonating & get a new or better crank/rod assembly
Im not sure where to even look for a new rod.
Any advice would be appreciated
Thanks
