The guy I bought it from I work with, he is a BIG GUY and he didnt really enjoy riding it much, he never modded it and didnt really ride it much, I took the sproket off and there was very little were on it also..... I have ran maybe 15 gallons through it and I run 4 oZ to a gallon of KlotZ. Tors is still on but is unhooked and it will fire on 2 or 3 kicks with the choke on. The motor has never been opened.
