I cut the wheel off the axle and now I'm getting the atv hubs turned down and keyed to fit the ends. This way I can use the several sets of 110mm rims/tires I have. I picked up the bearings and mounted the engine and jackshaft. I will the use the Predator 212cc at first since it has a gas tank (that don't leak). I have been doing several calculations with both 18" and 22" tires and will try them out with the 12t and 48t sprockets I already have. I suspect I will need to get a 10t to get the ratio to 4.8 instead of 4. I gestemated 3130RPM at the jackshaft from the Comet converter at top speed and 56.52 inches of travel per tire rotation. 1056 inches per minute equals 1mph, divided by 56.52 equals 18.68. Then I took the 3130 rpm and divided by 4 equals 782.5 then divided by 18.68 and got 41.88 MPH at top speed not including the loss from friction and drag. A 10t sprocket will give me 34.91 mph which is probably what I'll go with so I have more climbing power and should be able to use the 22" tires. That is if I did my 'figuring' right.
