You guys running higher than 15 p.s.i of boost , are you still using basically the same jetting as you ran at 8-12 psi of boost?

yup..... fuel pressure maintains jetting
Go big......I've had mine off the rev limiter above 20lbs.........sounds like an indy car off the limiter.

Do you mean you are hitting the limiter or you have disabled it? If so how do you disable it?

Might not be a good idea..... The valves will float at some point.

I'm searching for a discontinued Weisco piston for 1995-1997 Vmax 800. stamped 2360ps on top and stamped 2359 underneath. It is a stock bore replacement. Hoping someone may have it sitting on a shelf or drawer. I installed them in my sled 5 years ago and need a replacement without having to buy 4 new yamaha pistons. Call me at 269.369.8629 or email onrof@hotmail.com
