Is it possible to change the final drive ratio in the reduction unit by replacing the drive sprocket to one with fewer teeth?
If I wanted to do this, what would be the simplest and least costly way?
Buy a properly sized sprocket and then have a machine shop put the right # of splines in it? (I'm assuming a machine shop can do that sort of thing)
1) Yes - I don't see why not
2) In my opinion - I would buy an "A type" sprocket and then machine out the center to fit the original Honda spline piece from the old sprocket. Then I would machine off those old teeth. Then weld the new sprocket on. The machine shop will know what you mean when you say "A type" sprocket.
Caution: You need 1/3 rd wrap on those teeth or there's not enough engagement.
Caution 2: Short chains wear very fast.
3) I think Honda uses an odd spline count - not sure but if a machine shop has to do this then it's gona cost big. They would have to make a custom cutter first and then labor.
