400 swap in the very near future as the 250 has started smoking and the gearbox has been whining for a few weeks now.
Need some ideas on building a jackshaft and on gear ratios......also gotta figure out reverse as i refuse to drive a buggy without reverse.
Update i just got a polaris trail boss/blazer 250 and im seriously thinking about using its F/N/R box only issue is it uses 520 chain. I belive the polaris trans ratio is 2.5-1 in forward and 3 or so in reverse. Thats where im stuck tho is what size sprockets to run on the input and output shaft on the trans. Ill be keeping my 39t axle sprocket and would like to go with 25/26-11/12-12s. Also this motor has a torque converter like an auto car trans so there should be less "shock" load on the drivetrain compared to a normal motorcycle motor.....I think anyway. Any and all ideers and suggestions are welcome.
