Fun’s over, time to start some sh*t.
Running a shift kit is f’in retarded. Why would you go from having only one chain, to 3 chains all pointing in different directions? Introduce a great deal of things to go wrong and lose so much efficiency. And lose engine braking. Money and effort that could be better spent learning about 2-strokes and making the engine stronger. If you wanna shift gears manually get a motorcycle engine! At least it’s not going to be mechanically ugly! Keep It Simple, Stupid!
Fixed for ya...
