I recently bought a 96 GSXR750 to use as a trackbike and have been unable to fix an acceleration problem with it so any advice would be greatly appreciated.
The bike starts to accelerate fine but at different speeds (85-104mph) it stops accelerating even though it is only doing around 7000rpm.
First time out it would not go over 100mph, so I checked the speed sensor, air filter, fuel filter, gearing, replaced the fuel and checked the wiring with no problems found. Took it out again and now it will still start accelerating fine, but stop accelerating at different points, one time at 97 mph, another at 104mph, and another at 85mph. I did notice that the sounds from the white brothers pipe are smooth and even until around 75 mph, then it sounds a little uneven. Also when it stops accelerating, it is only doing around 7000 rpm so the engine isn't struggling to move my fat a$$. Also I have been doing the testing on a flat deserted road so the road isn't the problem.
There are no good shops in my area so I want to avoid them but the bike is to slow right now for a trackbike. My first guess is a jetting problem but I have only worked on streetbikes for 5 months now so I don't know much.
