Could someone give me a list of everything else that I need to have a Motorized Bike, excluding the engine and the bike. I might be able to customize some of the parts for free, for example: i could make a chain guard out of some scrap that I can find just laying around. I am on a tight budget, and I need your help. Although, I would like to have a jackshaft (is that possible to custom make?) and a tuned pipe? What is a "tuned pipe" btw and how much efficiency and/or HP will I get out of one? As you can probably tell, Im trying to be as cheap as possible, but still have a really efficient ride and possible performance. Thanks.
