I just finished a cylinderworks 435 installation on my 2002 s model supermoto. I also added E- model inlet and exhaust cams and changed crank pin, main bearings, cam chain etc and anything that was out of spec. I already had installed an FCR jetted according to Eddie's recommendations apart from the needle where I could only get hold of the emq here in Greece which is a bit leaner. I also had installed a full FMF Q2 exhaust. After running in the bike, I am not that impressed with the power increase. Its as powerful as when I had it with the S cams and standard bore. What can be the reason for lack of the expected power (no more power wheelies and less over rev)? I have kept the same jetting since now its around mid 30's and snowing so the main is at 160 and pilot is 45, needle on the 3rd clip. I suspect that the base gasket should have been set at one layer instead of three which came with the kit, but my mechanic insisted to keep it at three layers for more "reliability" as he says the higher compression will affect the crank bearing lifespan. Should I lower the main to the suggested 158 and or open the motor and get the base gasket to one layer?
