Common Q & A's:
Q: Do you recommend this upgrade with my stock exhausts?
A: There would be almost no performance upgrade as the stock exhaust would make the flow "bottleneck" as the stock slip-ons are quite restrictive. For the best bolt-on performance upgrade, we recommend this with an exhaust upgrade
Q: Can I still use my sidecovers or will this leave the sides of my bike exposed?
A: Sidecovers can be used after installing the Air Box Removal Kit
Q: Which jets in the carb kit do I use for my British Customs exhaust?
A: We've included more than one size to ensure you get a ballpark range to start off with; Jetting will depend on the location/elevation/etc. If you are not familiar with jetting, we recommend getting your carbs tuned through a professional mechanic to ensure a proper install.
