I bought a top end gasket kit the other day to go with my soon to be motor build and while I was looking at the package I noticed it said 104mm on the package. I know the bore size for the cylinder is 102mm. Any ideas as to what the 104 is for?

overbore size, it will probably be ok and on a lot of bikes it doesnt make a hole heck of a lot of difference with a slightly larger bore for head gasket. but the xx has a pretty narrow sealing area to begin with having the correct size is a good idea but that would probably work

I think ill just get the factory oem gaskets I want them to be right.

When i had my bb, i had custom MLS 106mm gaskets made for the 105mm bore. +2mm over the stock bore is pushing it imo. Get the oem gaskets!!
