i got my cylinder back from the plater. will be going on the dyno this weekend. i want to test different cylinder porting out there. i will test from stock cylinder to my cylinder set up. and then with stock cylinder with my kips valve assy mod. I know some people cut the main kips valve so it flush with the main port. but now you just toke away 5-6* away from the buttom exhaust port timing around 165*. That what i can up with. Now you lost some buttom end. i know some lift and drop cylinders. There is alot of improvement in these cylinder for the normal rider, that doesn't change the power band. no raising of any ports.
