I drive an APE 50 TL6T with an 85cc cylinder and a sport exhaust. This combination of original gears and 85cc gives me extra speed, but I still have little use of 4th gear unless I'm going downhill or have the wind in my back. After a few hundred meters, I will have to shift down to 3rd again.
I have been lookin at your input shaft/gear combos as well as your primary transmission combos. I am not really looking for more speed - rather more power for driving with loads and preferably being able to make use of 4th gear for cruising.
What parts would you recommend?
Do the reed blocks work with the original crank shaft or do I need a special one?
Please add more APE stuff and tips to your catalog ;)
