Looking for a thicker base gasket for my 04' XC800. I want to raise the porting slightly by going with a thicker base gasket. Anybody know of any manufacturers that have one? Any info appreciated.

:dunno:

You can get just about any gasket thickness you want at Cometic (www.cometic.com 1-800-752-9850). You need to know how thick before you call. I put thicker base gaskets on my 600xc but had to cut the head to regain lost compression. The gaskets had to be custom made but it still only took a week to get them and they were only $7 each ! The sled showed another 3.5hp at the track on my track dyno after doing this mod !! :banana:

I don't have any torque numbers but I do know that in a side by side race with my son's prox2 600 ,(dynoed at 118hp ), I pulled away from him right from the start to finish !
