1987 Electra Glide
Trike conversion
Stock front pulley (34T I think) and stock rear pulley (70T confirmed)
Rear tires diameter 25.5. The stock rear tire should be about 25.7 in diameter.
My rpm at 70mph is 3500. I am thinking it should be about 3000 or a little less.
I think the best way to adjust would be a smaller rear pulley. I can find a 65 T pulley. But I don't know how to calculate the result. I can find plenty of rpm/mph/gear ratio calculators but I have NOT found one to take pulley size into consideration.
I could go to a taller tire but at more expense than a rear pulley.
Any suggestions or comments welcomed.
