2. Spark plug cables in bad condition and leaking check for spark leakage in the dark.
3. Spark plug gap too close or too wide.
4. Faulty ignition coil, module, and or sensor.
5. Battery nearly discharged.
6. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.

SOURCE: How fast

Contrary to what the speedometer might say (and GSXR 750 owners), a 2008 GSXR does not have the displacement to reach 180mph. A road test conducted in germany had a rider reach 181mph - or what said 181mph on the speedometer - but was actually clocked on radar going 173mph. 173mph is what a GSXR will reach at around 1200 feet altitude and 65 degrees fahrenheit. Depending on the altitude and temperature, you might have slight fluctuations. If you want to go 180mph+, just get a GSX1000R

Tighten it until it strips and then back it off a quarter turn.

How do i remove the clutch sprocket cover off a GSXR750 2003. I already removed 4 bolts and removed the shifter but it still does not budge


If all bolts are out & there is nothing in the way of it being removed, then tap the casing smartly with a non-metallic mallet (around the join preferably) whilst pulling the on the casing until it frees
