bashplate Posted January 2, 2022 Report Share Posted January 2, 2022 Hi folks, just a question for future sprocket alternatives. I have a motor which is B40 cases, with B44 crank and top end, 23 eng sprocket and 52 clutch....gearbox is 11 teeth with 55 on rear. I'm guessing standard side point motor gear box ratio's, but no clue realy. So bike handles sections in first gear reasonably well if not realy tight, and second good for hill climbs, so quite usable. Was just wondering if I went to a 18 tooth engine sprocket....I may be able to go up a tooth or two on the gear box and less teeth on the rear and shorter chain, and still lower the overall gearing slightly. Sounds feasable to me, but any input welcome. My biggest worry is the 18 tooth would put more strain on the gear box with the oompf from the B44 grunt. Cheers, Bashplate.
