Hi, I'm riding in wintertimes a lot in places where traction is really poor and in current tune -05 450 has all too much power and torque to stick to the ground. Currently bike has 02 piston (11.5:1) and cam and + 9oz flywheel. Those helps a bit but torque should be reduced still especially from the low rpms. Any expecience mellowing more, eg. would there be even mellower cams, pistons and eg. pipes?
