changing the bars..

[Arctic cb1100_imp]

while I agree keeping the knobs is the better way to go if not installing pre drilled bars I have three motorcycles and have had others and and my cb is the only one I've owned that has drilled bars I installed renthal low's on my bike and opted to very carefully grind the knobs down with a demel to where they would bite into the new bars just a little bit when tightened down and they hold very solid and have never moved!
bikes and other atv's have been coming out without drilled bars and switch knobs for decades and still do and have done just fine!
