The UCE is one of the new-fangled multi-layer metal gaskets. Scott
.......... I'm not a fan of solid copper gaskets. They seem to blow out easier and faster than composite gaskets.
Were the ones you used black or bare metal?Scott
Boooooo Hey Ace! What can we do about these head gaskets!?Scottie
When they are new, they are bare metal. Stainless I believe ? After use, they turn black. They are similar to what you might see in a Modern car's head gasket... you know, like a honda or a VW ..... Also while you're at it.. I would consider putting in new studs. The stock ones ain't so great.... a weeeee bit of stretch in those threads. The same grade material as the rest of the hardware on the bike. I made up new ones while I was in there. Also, the plug threads aren't the best, and again, while i was at it, I heli coiled it.... with the good one's. You know, the black type ? Tap, install with lock tight, then tap and expand with the provided tool.
