Has anyone experimented with changing gear ratio between transmission (15 tooth sprocket) and lower rear axle (34 tooth sprocket)? This gives a 2.26 :1 ratio. That was at the time when the machine was equipt with a 2 stroke engine. Now with a 4 stroke, i have torque but not much top speed. I am going to go with a 30 tooth sprocket on the rear drive axle to give me a 2.00 :1 ratio. Hopefully i have enough for tensioner adjustment, since that sprocket will be smaller. Ive also changed my secondary clutch to a smaller 9". Any thoughts on this?
