Hello, i just got my A2 license and decided to go for a GS500F 04 model. The bike runs very good, but at high rpms (7-9k) it is very twitchy for a lack of an better word. Gas seems to come in small pulses, so the ride get very uneeven. I have tried switching over to pri and having the gas cap open, but this didn't seem to do the trick. I know the bike has disk restrictors behind the carburators, but i don't know if this has anything do to with this.

Does anyone have a clue on whats wrong?

Did another test, i can get past the twitchyness if i let go of the gas for a bit then turn it up again. It feels like im "pushing" trough the limit, and after that it's okay.

anyone messed with any settings on the carbs yet?
