I had to tear my engine apart to replace a bent shift fork in the tranny (write up to follow in the future if anyone requests it) and while I was in there I thought I'd play around a bit. Did a bit of looking around and saw some info on the R6 header gasket being slimmer than the FZ6. Mechanically this means there is less clearance between the valves and the pistons. This would increase the compression ratio of the engine and improve power and gas milage. I figured hell why not, it costs the same as the FZ6 gasket, and should have worked.
Well it doesn't. Physically the 04 R6 engine is almost exactly the same in dimension, even uses the same part numbers for the pistons and valves, but with the R6 gasket there is a compression leak, I think between cylinders I haven't pinned it down it's not important, it just won't work. Maybe the cylinder head mating surface is just different enough to cause problems, I dunno. Save yourself $50 and a couple hours, It does not work. :surrender:
*Update*
Well, it turns out it does work, my original guess was correct. After reading opnwhlmnd's post, I decided to try again. Worked fine. I don't know if the first gasket was a bust or what, eitherway it does work. Unfortunatly I had other issues so I can't give you any real feedback on the change. It seemed to have a bit more pep, but that could have been a mental thing. Dunno I may try again sometime and report back.
