FYI : The labyrinth O ring gaskets on RS/TM/CVK are 2mm OD, the groove they sit in is about 1.6mm deep X 2.2mm wide. Shown is a float bowl from a 1985 Canadian version GSXR750R which were early TM series 29mm flat slides.

 

The only downside of the rubber gaskets is when the are wet with gas they swell and will not go into the groove unless you heat the rubber to remove the gasoline. A few minutes with a heat gun usually shrinks them down enough to go back into the groove. Its a pain to do but if you don't the gasket will pinch somewhere and you will have a substantial fuel leak.

OK so after getting totally frustrated reading opposing information about Nitrile in E10 fuel I came to the decision that the safest option was Viton. The issue was sourcing 1.5mm sheet, Amazon and Ebay had no stock and most of the rubber suppliers I tried sell "by the meter" at approx $120 per meter. Finally I found a supplier that would sell a piece A5 size for $20. The rational forgoing with Viton is "apparently" it swells much less in E10 (less than 10% as opposed to up to 100% for Nitrile after prolonged exposure) That level of swelling is fine for "O" rings and would make a really tight seal but for these gaskets I was concerned that they would "pop out" as suggested by Ed or foul the floats as suggested by Clay with that degree of swelling. So Viton it is (time will tell how it works out ??)
PS: apologies for hijacking your thread Ed

Nice Clean cutting Wookie!! You might note, hole size as cut/shown for those 4 screws look a little small, might be rough getting the M5's to start? Have you tried to fit them yet? You'll note the area around the float posts is the hardest to get right. Great Job!!
