Geeeez Doc...now you've got guys rubbin their hands together all over the globe!!
Depends what your end goal is really...My advise is to have a finished goal in mind cos its so easy to swerve off the line and the whole thing changes....Some, like Steel said, do the Carpenter thing which is awesome...others just want something less. (less is more, in this case.)
I have Gutted the air system and added K&N Triples, added crossover, added Jardines, added PC5 and tune plus numerous other things... bars, grips, led lights, seats, bacrest and rack, mirrors, risers, hiway pegs, and now suspension.
Others here have done similar if not more so there is a huge amount of advice in these pages so ask away...the internet is your oyster!
