Hi guys. I've been building my motorized build from the ground up...so to speak. I slapped a 79cc Predator on a 21-speed. I removed the crank, using the bottom bracket to build a jackshaft ( 5/8" shaft 9"L 5/8" presicion bearings [OD 1- 3/8"] meshed int the original ballbearings). NO PEDALING ALLOWED. All was going well until the last two steps - mounting the drive sprockets and drivetrain! Temporarily I wanted to power a gear mounted on the leftside rear wheel. Ultimately, I want to drive the bike gears. My problem is broken down into both short term and long term. The short term problem: The leftside 9 hole - 32 teeth, dished sprocket takes #415H chain but I can't find a 5/8" bore keyed sprocket to mount on the jackshaft.
The long term problem: I can't find any sprocket to mount on the right side that fits the multi-speed bike chain. I need help!
The long term problem: I can't find any sprocket to mount on the right side that fits the multi-speed bike chain. I need help!
