Installed my full Tyga race system a while back without jetting. The bike did not run right. I only ran it in the driveway as it would barely rev past 8K and then with feathering the throttle. It was wishful thinking on my part that I could get away with just removing the snorkel. I went ahead and installed a Dyno Jet stage 2 kit and set it up per instructions. The bike ran pretty damn good when I rode it in my neighborhood
. I'm sure there is some fine tuning that can be done on the dyno but I think that can wait for now. Want to give props to Tyga and say I'm really happy with my purchase. This is a really good quality, awesome looking exhaust for a good price.
