Why is the 90* gearbox needed with a horizontal shaft? Also, thanks for the info on the transmission. I didn't know about it and it'll be great for my project.
Ok thanks for the info on the CVT. I'll look into using one. About the manual transmission, I don't completely understand what you mean by the 90 degree rotation between the input and output shafts. Could you explain it again? Sorry.
So I'm thinking of making a go kart using a Predator 212 6.5hp that has a 2 or 3 speed 1 reverse (at least one gear high torque and another high speed). What sort of clutch should I use and how would I figure out the gear ratios for the transmission? Aiming for 45 mph top speed. Thanks for the help.
