GSXR 1000 Issues in JR Comp Dragster
We have a 01-02 GSXR 1000 set up in my sons JR Comp Dragster...its 100% stock except for the slyder clutch. We have ran it for over a year with no issues but now...
If you raise the RPM over lets say 5K when the engine trys to return to idle it will drop way down in the 800 RPM range and start to black smoke and sputter for 5 or so seconds then it clears up and will come back to idle.
Its also way "Fat" or rich when I do this, we have never had this issue and I have changed what I can such as fuel, fuel filter, plugs and checked the Fuel PSI ( 43 psi)
Can anyone give me some advice on what to check...injectors, sensors, etc ??
