The 2XT head gasket is an RZ 500 part also 47X 11181 00 and the earlier bikes were 1KT 11181 00. Is there any difference in the gaskets and can I run a 1KT gasket instead of the 47X one.
the RZ500 one is thicker than the 1kt one.
I'd fit the 1 kt one and check the squish and go from there
Cheers. I just got my Yambits gasket set in the post and just looking at the two the only difference is the size of the hole that I am pointing to with the pen. That is the old 2XT gasket and the holes are bigger, I haven't opened the packet to check the thickness. I have a genuine RZ gasket spare so will fit that.
