My friend has one, im supprised its still going after all the problems its had, hasnt even been on road for a year yet.
Problems so far,
Top exhaust bolt from engine snapped, and was held on with gardenning wire,
Exhaust pipe somewhere was bent and air was leaking badly, meaning lots of noise
Indicator relay broke
Chain came off several times as the tensioner bolt was siezed on and snapped when he tried adjusting it. he got replacements now
ehhm.. what else.. Oh yeah its already rusting like hell.
