I am using Wossner 13.5:1 pistons and a 0.55mm head gasket, no head milling, Web camshafts (the milder of the two available choices) and I undid the 3-degree timing advance that I had before building the engine. With those pistons, 0.45mm head gasket would have put piston-to-head clearance scary tight. Maybe the stock pistons have a slightly different deck height but you'd better check. Unfortunately, the 0.55mm head gasket appears to be no longer available.
I've done all of my tuning on PetroCanada 94, which is what I plan to use whenever possible, and there's no detonation as far as I can tell. Had one fill-up of Shell V-power 91, it didn't feel right and I was nervous about it ... I'd rather not find out the hard way that it wants more. At this point I'm planning to run it on 94, and I can use 91 if I can't get 94 and need to get somewhere, but not riding hard ... I just finished resetting the valve clearances after putting about 1000 km on the engine (and deciding that I'd rather use Kawasaki's valve clearance specs than Web Camshafts much looser, excessively noisy specs), we'll see if that changes anything tomorrow.
Helibars, MRA screen, Ohlins damper, reversed shift pattern, sorted suspension, braided lines, Michelin Pilot Power, all else stock 'coz it's fast enough!
