Aloha, As the title states I've had my motorized bike for about a year now, shes a fankin-bike to be sure. I cobbled her together form three diffrent mountain bikes, a poor choice I know but its what I had, and strapped on the cheapest 80cc kit that I could find. I am currently engaged in a full tear down becasue she made the most aweful noise before loosing power. That heart stopping grinding noise that left me with the inclination that something was terribly wrong in the piston housing. I cracked her open to find metal shavings in the piston chamber, my suspisions were correct. So why the full tear down? Well its a cheap motor and I want to be sure nothing else is wrong with her, I will also be investing in a proper cruiser frame.
