Are you being serious? I've seen the KSR110 4 speed shift drum and the tolerances are crap compared to the aftermarket offerings... That's the 4 speed shift drum that people are using unless they are modifying the stock unit to become a 4 speed shift drum.
And how's that stock Kawi output shaft holding up on big displacment motors?
I'd go with one of the aftermarket units and skip the Kawi 4 speed drum.
