Hot Cams with 13.5:1 piston

Are there any know issues with running the 13.5:1 pistion with the hot cams. I don't want an issue with the valves hitting the piston.

Thanks,

I run both and have had no problems. I think its a good combo. The Wiseco pistons are a little louder than stock (piston slap) and it does take a harder kick to fire it up, but its worth it.

Thanks :D

I currently run Wiseco +2mm overbore 12.5:1, for almost two years now. I'm going to go through the top end again and wanted to try the 13.5:1.

Thanks for your feedback.

nice bike!!!!!!

Do you run race gas with that piston...or does 92-94 octane premium cut it without pinging?

I've heard of guys running pump fuel with this set up, but I run race fuel. I use Citgo's 110 leaded fuel, I used it when the bike was stock also. It seems just a little more crisp with the leaded fuel.

Thanks :D
