I'm far from an expert just relaying what I did when I put the V&H 2" rise bars on a few weeks ago , the stock front brake line isn't really an issue . I drilled the bars and instead of in a vise to avoid scratches or inverted bolted down in the top clamp/ risers . I figured the best route was to hold them down on a garbage bag in the kitchen with one hand and use center punch to give a good guide to where to walk your pilot hole drill bit all over the place with your drill in your other hand and then have it move around on the bag to rub in the metal filing for extra scratches. Lined up the holes inline to the stock holes for the wiring clips . The clutch cable does have a few extra inches on it, I just adjusted it and zap strapped the line after adjustment out of the way as it could possibly get pinched by the triple tree's . I plan to buy a Barnett high performance clutch cable that's a few inches shorter ( like $60-$70) and swap the stock one since I pinched it good when I turned the wheel fully left while checking the throttle adjustment . I'm pretty sure the V&H race kit part is a Barnett high performance clutch cable , have to verify the part #'s since the [email protected] parts Canada catalog doesn't seem to match the V&H part #'s contrary to their customer service claims. Basically if your worried stock bars are 6" rise so 4"ish excess depending on which ones you choose . In my opinion you don't need to replace either , I've rerouted clutch cables without issue on other bikes as long as there not binding anywhere or dragging low , good to go .V&H sells clutch/throttle cables that are shorter for the bars but again there is cheaper ways and it's not necessary.
