Do you have stock body work? Keep the kickstand?
The shift rod attachment didn't clear the body work. Shims were needed. The shift lever nut that screws in through the kickstand is designed to be used without a kickstand and we had to manufacture a new part. Then the shift lever was hidden from the footpeg, so spacers were needed so that your toes can actually click on it. The heel guard has adjustments on them, which are not adjustable. Only 4 of the 6 footpeg positions on the left rearset can be used if you use the heel guard. On the right rearet if you don't want to relocate the entire break master cylinder, and want to use the heel guard, then spacers are needed so that the rearset doesn't rub on the exhaust guard. if you use the heel guard, then there is no where to screw it in unless you use two of the footpeg holes, meaning then that only 3 of the 6 are useable, and the bottom ones only. Both heel guards have to be bent into a new shape or they hang on your boot.
The shift lever cam arm at the top of the lever - cannot be tightened as it was intended because there is no clearance between it and the frame so it had to be remachined. The screw doesn't lock the cam onto the bike as every other system out there does, so check its tight regularly.
Basically, of all the different brands of rearset I've used over time, none have been this poorly thought out and designed.
I have photos documenting all of the problems if anyone wants to see them.
