Hey guys im new to the forum, i was pointed in this direction from a member of DIY Go-kart. I have been surfing some threads and found alot of helpful info.
I have a 20 inch dimondback that i plan on mounting a chainsaw to. Its a homlite C-72, its 80cc, direct drive, Meaning it has no centrifical clutch.
I plan on welding a frame up that i can mount to my seat post area with U-bolts so i can remove the setup if id like. I will use turnbuckles to adjust the force of the spindle, i plan on using a large spring with the turnbuckle so i can pull a lever and lift the roller from the tire like a clutch system. I know how to hook up all mentioned above and throttle, killswitch, ect.
My main question is my spindle size im new to this area of "gearing" i beleive the main factors are RPM and spindle. Ive read a few post on how tire size dosent really factor into the gearing. It an average 20inch steel bike frame, im around 130 pounds and the mount/frame and chainsaw probably will weigh 20-40 pounds. (not real sure). Its all flat land and if there are any hills they will be pedled up. Also, it will be a pedal start so the gearing dosent need much as much tourqe. I want to be pretty fast probably 35-45 mph, im not sure if this is acheiveable? What should my spindle size and gear ratio be?
