He is currently running a 37 tooth rear right now. I also have the 33 tooth rear that GreenJoe sent me . I'll run this setup for a bit and test it. I'll post the results shiortly.
all the best L&S

Given that you said that with the stock final drive gearing 14/45 you were turning 8500rpm at 75mph by my math you would be turning 6800rpm at 60mph so the present 15/41 final drive gearing, drops the rpm to 6000rpm or 12%.
How is starting out on hills with the new gearing?
Have you notice that your ability to maintain a high speed against hills and headwinds has been deminished in 6th gear?
