boot to reed cage gasket
1FAST450R:
everything looks good besides the head gasket. they used some sort of gooey sealant on it. its redish in color and becomes soft when the engine comes up to running temp. i might just do a top end rebuild before i ride it again to get rid of the red junk.
Foxx4Beaver:
yeah, there should be no sealer on the base gasket.
when you order your gaskets, go with Cometic....they're a metal gasket, and they have a rubberized coating on them, that acts like a giant o-ring....they won't leak.

PM alward25 too...I believe he gets the base gaskets with the smaller holes for the KIPS valves.

I mis-read this the 1st time...I thought you were referring to the base gasket.
there still should be no sealant on the head...my guess is that the head could be warped to some degree, and/or the cylinder's mating surface isn't flat...you'll need to pull the cylinder studs, and lap the cylinder and the head until they're flat.
Might as well toss in new cylinder studs, and new head nuts too....and with an OEM or Cometic head gasket, it won't leak...unless there's another under lying issue...i.e....a crack in the head.
1FAST450R:
I pulled the head off and they just put sealant around the outside edge of the cylinder. but what I found inside is concerning. there is a crack between the kips port and the exhaust port. that should be concerning right? I think it would be time for a repair, replate and top end.
