I'm installing a set of 10" KST Renegade bars. Inside the front halves of the clutch and brake perches, there is a tit that engages into the stock bars that are drilled for it. On the KST's it's not drilled there. Not sure if all the aftermarket bars are this way. Do I need to grind off the tit? Can't see drilling the bars, KST would've done that .
