the kickstand will hit pretty much all puch aftermarket pipes (except the simo and custom stuff that puts the pipe into your seat lol)
the solution to this is to bolt on a small slab of metal between the kickstand and where it rest when retracted. Using one of the kickstand mount bolts and position that metal slab so that when the kick stand flys up it is between it and the mount. Kinda hard to understand.
so u mount it right where the kickstand mounts. now the kickstand has 2 tabs on it that rest upon the kickstand mount and dictate where the kick stand rest in the up position. if you bolt that metal slab inbetween one tab and the mount when the kick stand flys up the tabs will hit the slab and stop it from fully retracting upwards (only like 1") this is just enough so that it no longer bangs the pipe when you flip it up.... get it?
