Hello everyone. Finally got around to dyno testing my set-up. While i was hoping for a little better numbers without the bottle,i can tell you she is one sweet ride. What i mean by that is the driveability is excellent with no flat spots hits farts ect. The engine starts easily under the most severe of conditions gets 40+ miles to the gallon and if you don't like to flog your engine to get up the steepest of terrain with the significant other on the back this just might be the bike for you. With the Zippers N.A.D.S. system when the most irritating pos comes alongside with the attitude that he or she is from a superior part of the planet you can unleash some serious attitude of your own! Then once that's taken care of you can go back to cruising with a very sweet running chariot. No leaping,jerking racing cams, no detonation issues, longer engine life(very important when you void the warranty like i have done!) Anyway have a look at the dyno and i can tell you these numbers were achieved with the mildest nitrous settings, there is more on the table. The H.P. is suffering due to the restrictive exhaust.
