Question about 1990 Suzuki GSX 750 F (Katana)
I have a 1990 Suzuki GSXR 750, the problem I'm having now is after about 15 minutes of riding my bike stalls. I have recently had the carburetors synchronized but that did not help. Has anybody else had this issue? Any advice would be great, I don't want to take it to the shop again without the problem being fixed it's too expensive.@
Hi, Jsjss5 and the usual suspects are:
1. Severely discharged or a damaged battery should have 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage the battery is faulty and must be replaced, AGM batteries fail in this scenario more so than lead-acid batteries.
2. Failed alternator/generator and or voltage regulator.
3. Loose or corroded battery terminals and or cables especially the "NEGATIVE" cable, look for loose, corroded, or broken connectors inside the cable harness at "BOTH" ends.
4. Failed main circuit breaker or ignition switch, check for loose connections and continuity.
5. Failed system and or ignition relay, check for continuity.
6. Failed ignition coil, stator, magneto, ignition/electronic module.
7. Failed CKP, CPS, CMP, MAP, TPS, or BAS sensor, corroded, loose or broken wire connector pins/sockets.
8. Throttle cables and or idle speed improperly adjusted hot idle speed should be 950 RPM to 1000 RPM.
9. Faulty neutral, side stand or clutch lever safety switch.
10. Air/fuel mixture screw improperly adjusted.
11. Accelerator pump damaged or not working.
12. Water or dirt in the fuel system, carburetor or filter.
13. Restricted, blocked or kinked fuel line.
14. Fuel tank empty.
15. The gas cap is not venting properly or fuel tank venting system blocked.
16. A failed fuel pump, pressure regulator and or fuel injectors.
17. Vacuum line from intake manifold to petcock broken, cracked, or not attached, carburetor vent line plugged.
18. Needle and seat stuck closed in the float bowl.
19. Lean angle switch is faulty or needs adjustment.

could be few probs, carbon build up on piston crown try a good cleaner fuel additive, your exaust is leaking or blowing allowing air to be sucked back in on revdown as well as you could have a inlet fault overfueling leaving to much unburnt fuel to enter your exaust, might be simple fix by just replacing the air filter and checking for burn marks around the air intake.
