Greetings comrades, I'm contemplating the purchase of one of these fine motorcycles, cheap (because its been down the road) as a track hack. apart from the considerable damage to all plastic it has also had the alternator cover, stator and crank sensor taken out. The rotor does not appear to have suffered (although I am a bit aprehensive about the crank taking a knock), but I do see that a "race" conversion is available. Weight is down 4Kg and is supposed to run up a bit quicker. Any of you folks had any experiance with this conversion?
