I am a total newbee to this forum but not dirt bikes (coming from a Honda XR650, Maico 250, and Yamaha 125). I just got the green machine new 08 KLX450. I put a new battery and battery tender harness on it because the brand new battery was dead and would not take charge right there in the shop showroom. I may even disconnect the headlight or put a switch on it so the charger will work better. I have JD jetting kit, sprockets, oil, and filters, fork springs, and shock spring on order. I could not force myself to pull the trigger on exhaust. I am after XR650 type low end power if possible (and could care less about high rpm power) if anyone can give me a hint on exhaust or mods I would appeciate it. Also, I need to block off the AIS but can't find anything in the TT store. Anyone know of a link?
