I can sense that the rear wheel and cassette are protesting and MIGHT be a problem. It has OEM spokes back there, while the front wheel is HD with 12g spokes.
A spare HD Staton rear wheel with 14gauge SS spokes and brand new 8-speed cassette will be installed. Its gearing varies greatly with what is on the bike now. Here are the differences, with engine rpm/mph at 5000rpm and 10000rpm:
1st gear - same at 32-tooth, gear ratio = 41.64:1....10.2mph @ 5000rpm/18.6mph @ 10000rpm
2nd gear - 28t - 36.45:1...10.6mph/21.2mph(now at 33.84:1/12.6mph/22.9mph)
3rd gear - 24t - 31.24:1...12.4mph/24.8mph(now at 27.33:1/15.6/28.3mph)
4th gear - 21t - 27.34:1...14.1/28.3(now at 23.43:1/18.2/33mph)
5th gear - 19t - 24.73:1...15.6/31.3mph(now at 20.83:1/20.4/37.1mph)
6th gear - 17t - 22.13:1...17.5/35mph(now at 18.22:1/23.3/42.5mph)
7th gear - 15t -19.53:1...19.8/39.6mph(now at 15.62:1/27.2/49.5mph)
8th gear -13t -16.92:1...22.9/45.7mph(now at 14.32:1/29.7/54mph
HYPOTHETICALLY, in 8th gear, rpms can be increased to the GP460 engine's maximum peak hp at 11000rpm to increase speed to 50.3mph.
Gear ratio is much closer and more even. This engine should REALLY do well with this cassette!
