I am doing some standard tune-up on my two-speed Kreidler, which I bought recently. I would like to change the transmission fluid, especially since it tends to go GUH-GUH-GUH-GUH-GUH when changing gears. I was wondering if someone could give me some advice on this: What sort of transmission fluid should I use? How much? Any tips/hints on how to do this? Is it simple and straightforward or will this be a long and difficult procedure?
Any advice you can give will be very helpful. Thanks!
