Hi Miles,
Sure is a lot of work in designing & testing new products, and many have no idea of the hours involved. I really liked the way the shifter worked on the test unit, and was really simply in design. A simple tapered plate with 6 rollers forced the inner assembly towards the plantentary gears to make the shift. I think changing the angle a little may make the shift less aggressive.
I tested the drive on one of my modified Whizzers, and possibly the power was too much and caused the harsh shift. It worked real smooth under normal throttle.
I like your shifting speed of 12 MPH better than the 18 MPH on my test drive, and my concern is changing the plate angle [less aggressive] might make the shifting speed even higher. Oh well, looks like more work is needed.
I did take the bike up to 50 MPH several times and the balance of the unit was very good, no vibration, and minimum noise. The test unit is belt driven on both ends and pulling 9.03 X 1 final ratio. I know the ratios will need a major change for the 49 CC 4-stroke, and I think 14 X 1 would be closer to correct.
Looking foward to your test results. What are your final ratios? Are you using rear belt drive?
Have fun,
