I've had this huffy cranbrook for about half a year and it has caused me a few headaches. First 50 mi. it rode silky smooth with a good amount of power, hit 36 mph. Then the intake studs basically fell out. Replaced those with standard thread and rode for a bit until today when the right intake stud needed replacing again. Fixed it (sorta, I couldn't fully tighten it or it would unscrew out), and went for a ride. Barely had any power and the sucker smoked like a magic show. Came home, unscrewed the head nuts, and out came the studs for the head. What to do now? I'm thinking of replacing all of the hardware(+studs) and getting a new top end. Would it be smarter in the long run to just shell out the money for a new motor?
