Regarding the above mentioned top speed, l think l should change the gearing to make that a little more sensable.
So here’s the dilemma;
Drive tires are the same OD as the original MC tire, within an inch or two. So top speed should be within an inch or two of the donor. (Strictly mathematicaly)
The plan is to leave the gearing stock for reasons of clearance, chain and routing as well as adding a chain tensioner/adjuster thingy And the expense.
lowering the gearing enough to make a difference would involve finding a huge azz sprocket for the axle. Then the low gears (6speed) would become useless.
They only way l can figger would to be lock out one or two high gears.
I can't think of practical way to do that. So l guess some restraint will be required on the part of the operator. That'll be easy.
