I bought this bike today and it only lasted the day... I was putting it through its paces accelerating in 5th gear when it made a distinct POP sound and the engine just died. Its got spark & fuel but I then pulled the plug stuck my finger in the plug hole and cranked it over and felt no pressure/compression at all. Doom and Gloom! I know.. I'm going to strip the motor down for a look see but I really need a workshop/repair manual so as to check/compare tolerances. I cant find a manual for this bike anywhere online.. anyone know where I can get one? I reckon the guy that sold me this lemon musta had an inkling this was coming.. Thanks people.
