How is the high speed 4th gear performance?
Obvious, it will be faster, however you need the horsepower to attain higher speeds. Power on up-hills at speed in 4th gear is also compromised. This upgrade is recommended only on the 32 hp OHV engines. Big Bill’s Bikes installed the high speed 4th gear as standard for premium restorations. Most of the local Beijing riders use 24 hp engines, on the weekend rides into the mountains there have been complaints of not enough hauling power with the high speed 4th gear when going up hills.
