Hello Im new here and was wondering if anyone could help me. I just bought a 33cc chainsaw engine and planned on mounting it onto my bike and using the current gears on the bike to drive it. I have a mountain bike with 8 gears but a derailleur made for 7 gears so i have one thats useless, and its the largest gear aswell. My question was with 26" tires, 6 teeth on the drive sprocket, and 32 teeth on the sprocket on my bike, how fast would i be able to go? Would I have more torque or horsepower, and would this even be able to push me like this? Ive been reading articles and I just cant figure out how the ratio works, I even downloaded a program someone here made a gear ratio calculator and it tells me Id be moving 43mph at 3000rpm which I just cant see to be correct. Everything I was reading was saying 20:1 or 30:1 and mine is a 5.33:1 so I dont know the difference, could anyone explain? Thanks you!
