Alright so I just purchased a 2001 kdx 220r it's a great bike but it didn't come with any goodies all stock, and like most stock bikes I know there are always improvements that can be made. I however don't know to much about the mechnical aspect of things so I was wondering what mods would be ideal for this bike if it's used for all types of offroad riding? How could I tell if it needs jetting and other adjustments, or could I just bring it to a mechanic and tell them how it's ridden and they would know? All adjustment and mod suggestions and information is greatly appreciated, also which mods should be priority? I will probably only work on one thing at a time.
