Problems GSX 400 E

Hello, unfortunately I still have some problems with my GSX 400 E (GK53C) Bj.83! The following problems exist; 1. when I start the motorcycle it runs only on the left cylinder (seen in the direction of travel) and after a certain time only on the right cylinder 2. the problem still exists as already described here! http://www.motor-talk.de/…/…t-slow-back-zurueck-t2034436.html I already sprayed start pilot on the studs but did not detect any change in speed, w can that still be?? Or can it be that both problems have the same cause?? Can you help me? I don’t know anymore!! 🙁 Thank you very much for greeting Pätrick
