XR400 head gasket in 400ex

[cals400ex]

anyone used the XR400 head gasket on a 400ex. if so, did you notice any gain by the increased compression. also, i am not familar with the internals of the engine so how hard is it to install this gasket? what needs to be removed to replace the gasket? thanks

I have some extra XR gaskets laying around and I have been wondering the same thing

[jb400exxx]

does anybody know if the XR gasket will handle 11.1:1 compression w/o a problem or is it not a strong enough gasket? and what is good if the xr one isn't? i want to get high compression but not blow gaskets.

It will handle it just fine! Go for it mine worked great and was really realiable.

I got one delivered with my HRC racing kit . ( cam , 11:1 piston , outer clutch basket , etc ) .And IF HONDA RACING COMPANY delivers it with a XR gasket , it means something .

I raced a whole seazon with no probs at all ..

[YZROOSTINYA]

there is no diff betwen 96-03 in the xr head, any year will work
