So my sweetheart (Kawasaki zx6r 600F 95er) is jerking, if I let her roll out or drive at constant speed, then this is not the case with the acceleration. Have looked and the rear wheel bucked freely,I noticed that in certain positions (so sit there and turn on the rear wheel by hand) the chain is more punitive, than at other positions. Is that the reason for the jerking? Do I just have to renew the chain now? If I do the kupplun during the ride I think it’s the chain,but now I want to make sure if it can also be a camp, which causes the jerking. How can I check that, should I just loosen the chain and try it out? Tips on the chainkit purchase? Wanted to grab when the DID chainkit, since they promise a great quietness, someone experience with it? Greeting and thanks in advance Patric
