- Q & a
Do I have to change the jetting to use these. What would you recommend I do to get the best performance out of these slip on's?A:Excellent question! You will need to rejet your carbs in order to run these properly, as well as perform a couple other quick and easy upgrades.
To get the best performance gains, you will first need to install this air box removal kit:
The kit includes jets, and we recommend using a 140 for the main jet and a 42 for the pilot jet.
We also recommend installing an air injection removal kit to keep the exhaust from popping every time you decelerate: http://www.british-customs.com/modernclassics/triumph-bonneville-t100-carb-2002-2008/triumph-motorcycle-air-injection-removal-kit-html
