Hey i have one, no major problems but when i got it the back brakes didnt work, i needed 2 bleed them nfi how to do it so i emailed him and he explained very clearly, running like a carm, just when u get it change the spark plug 2 a good NGK 1 and ur fuel filter... my bike isnt working atm but will be.. coz of the back axel while i was tightening/undoing the threads got screwed up so im gonah order another 1 or 2 just for spares..
BIKE is excellent, very fast.. i got it to 82 km/h all stock just cruzen nxt 2 my dads car.. its quiet on idle ( i live in townhouses n the neighbours dont hear it) but when u open it up it gets loud lol..
cheers, Nathan.
