After building my first bike with a China bike kit, adding a SBP shift kit, and ending up spending 1300 bucks in total on the bike with a not very satisfying result, I have decided to sell my bike and build another based off a Harbor Freight 212cc engine.
I have heard really bad stories about cheap frames being destroyed by these big guys, and I built a go kart with one so I am well acquainted with their power (and potential destructiveness)!
Therefore, I want to go about this as systematically as possible. After hitting up the Scotto threads I feel that I have a better idea of a good, methodical way to go about this.
My three questions are this...
(1) I am planning on between a 4:1 and a 6:1 gear ratio. I am a 140lb rider and we have moderate hills around here, but I know that these engines don't lack for torque. Thoughts, questions, comments, concerns?
(2) I really want suggestions on a good bike FRAME that will be able to handle this engine. I'm going to mount the engine horizontally; I know how to weld but don't trust my skills enough to do welding on the structural components of the frame.
(3) I'm planning on a budget of about 6 to 7 hundred dollars for this build. Anybody think I'm out of my mind?
