Motor can overheat and seize in early models due to small radiator. Later bikes reliable in 12hp form. Derestricted by removing washer in the exhaust and enriching carb. Handling gets worse with age, lots of awful ones out there. Many ended up with written off engines at 25k, chassis bearigs also dead. Tread with care!
