I have been reading a ton of reviews and forum pages and there is just so much that can be done with the bikes. I was going to get a pair of rear sets from woodcraft and turn signals from ASB. I want different hand grips also and am wondering where is the best place to start with performance mods i.e. best bang for your buck or must do's? Any ideas or suggestions would be excellent. I was looking into exhaust but have read mixed reviews, not sure what pipes will give you the best performance over sound.
