Its difficult getting the shifter linkage set up, cuz of the lack of clearance wiht the pipe. They work better with stock pipes,as the expansion section of the pipe is a bit smaller, but ive got 2200 miles on htis set. Ive since put an offset bend in the shift lever to go around the pipe. Its about 10 degrees here in michigan so ive yet to put it back on and try it. So far I love it.
Ive sold about 4 sets so far with the no issues. Most complain about the tight fit, but they understand why it is hte way it is. Once i prove out the offset lever, Ill send out a new lever to everybody that bought a set from me.
Im working on sets for XS650 yamaha's , and CB750's too.
