The only catch is there is no engine braking, when you let off you are basically freewheeling like you would be on a single speed bike with an automatic clutch. My Hueng Sheng 4 stroke is the same way. It's something you just have to get use to. What is your ride?
My daily commuter is a Diamondback bike with AVID BB7 203mm disc brakes. Powerplant is a 2.8hp Tanaka 47R engine w/Tanaka 3-piece pipe through a shift kit w/8-speed cassette. Low gear is 37.09:1, which is good for steep parking ramps and gridlocked traffic of steep hills. Cruising 5th gear is 18.55:1 or 6th gear w/16.36:1. Cruising speed is 35-40mph.

Fear is the limiting speed factor.
