Hello to each other. I have been a proud owner of a 1993 GSXR 750W since a few weeks. Smaller defects, such as rattling steering dampers and similar things have already been fixed. However, the motor running causes me to break my head. The following problem: When I roll through a village in 4th or 5th gear, and then pull it up at the end of the village, it simply does not attract. It starts to mock and spit up to a speed of about 5000 revolutions and sounds like a throttled mofa. BRRRRRRRBRRB RRRRRBRRBRRBR. From 5000 rpm everything is normal… the following was done: spark plugs new air filter new carburettor cleaned, adjusted and synchronized. Half everything nothing. I also set the carburettor to the set value of 1.25 i.e. 1 1/4 revolutions. Man might think that it would run too fat in idle and partial load range… carburettor membranes are perfectly fine. False air doesn’t pull them either. round setting to run fat??? Thank you. MfG.: Matze
