This is what I do. With stock compression on a 2008 or newer engine . Start with the 88 to 94 ignition module timing that was set at 42 deg. Stock for an 08-12 is 35 deg. Set your timing to 42 across the board. 10 up to 3500. But 42 deg all the way to 16000 rpm then save. You must save . Ride it and see how it goes. Jetting the carb at 112 keihn jets . Maybe a shim under the needle. If you have a flat spot around. 8000 rpm add a deg or two from 7500 to 9000 and you are done. I have spent hundreds of hours on the dyno playing with the BRT ignition system . It rocks . Don't go over 44 deg and also use cooler plugs
