Kevin,
I have found that the best way to go is to move all your levers, grips, and accesories as far to the middle as you can get. Then cut off the excess. Careful on mounting anything on the bend itself, since it will not stay put. Also, make sure you mount everything so the throttle snaps back freely. The bar manufacturer will tell you what the minimum length is on the packaging, some are 27 inch min. If you run tight woods like I do, you will find that the less bar you have hanging out there, the better. Good luck.
