Hi everyone, i'm in the process of building a sodi kart with a 2005 crf450 4 stroke engine, i have the engine mounted on the kart chassis and i'm trying to work out the best route to go with chain and sprockets, i did initially think it would be best to just use the gearbox sprocket and chain from the dirt bike, 520 pitch but after seeing a few other comments on threads i'm wondering if i should just go with the 428 pitch chain, the axle on the kart is a 30mm with 6mm keyway, and the split 428 pitch 30mm sprockets are readily available, but i'm not having any success finding a 428 pitch sprocket to go on the crf450 gearbox output shaft, this has 17 splines.
Can anyone advise on a sprocket that would be suitable? is there off the shelf options? also would the what number of teeth on the rear sprocket would be about right gearing wise?
Any help appreciated.
Thanks
