I'm currently in the planning stages of a board track racer project from a 700c hybrid bicycle I acquired a few years back. The plan is to use a Predator 420cc motor and build it up over time for as close to 30+ as I can get. I have not been able to source a TC or CC (besides Noram Tri-Lobe) that can handle the kind of power I am looking at. I could always do a direct chain with no clutch and have to restart the bike after I stop, but this would be highly inefficient and make racing (if I ever go to the strip) difficult. So, does anyone have exhaustive knowledge on something that would meet my criteria?
