yeah man stock the 650 is a dog, I went with a white brothers exhaust, carb, and header, also a K&N filter... it livened it up alot... Though I rhode a KTM stock the other day.. the shit made my honda feel like a minivan. They just don´t make em like they used to. My 86 XR 600 was heavier, but can pull it up in 3rd with stock gears and parts. You don´t have to buy all the aftermarket crap to make the bike non handicap.
