Im running a stoke bore wiseco with 91 octane and some octane boost in the summer.

 

I am running Wiesco 11:1 102 mm. People talk about how Ross and JE pistons are heavier than stock. The wiesco was not. If anything it was lighter. So it will be easier on the stock rod.

I had the skirts friction coated and the dome coated with some cool smooth stuff.

 

Glad to see a few more wisecos around. I could have sworn there was only one other bike running a wiseco on this board last winter when I intsalled mine.
