Mickey Dunlap mentioned the use of a sealer in place of the base gasket and an xr400 headgasket to give you a true compression and better burn. Has anyone done this, does it work good, and does it affect the mounting of the top motor mount???? thanks.

Well , I installed the HRC kit last friday . I used the XR400 Gasket and it works just great ... DO NOT USE ANY SEALANT BETWEEN THE HEADGASKET . If Honda doesn't do it , why should you ?

Not on the head gasket, IN PLACE OF THE BASE GASKET! Anyone tried this?

The oil passage that feeds the upper end goes thru that gasket, so make sure it's not plugged with sealer if you're not going to use the gasket. Might be a good idea to put the sealer on sparingly, let it gel up for a while, then trim it away from the hole (before assembly). Don't forget to put the o-ring back on!
