Question about Suzuki GSX-R 750 Motorcycles
Hi, i have GSX-R 750 for some reason while riding bike just makes noise loose power and cut out, did it the day before it came right after a while and did same today. Where do I start looking for the problem. I found some light wires were worn through and they melted some fuses and wires but replaced them all. The battery had a 20 amp fuse that was melted away so can it still be electrical or is it mechanical? Can someone please help? Thanks
Hi, Robert and the usual suspects are:
1. Severely discharged or a damaged battery must 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. Faulty 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. Faulty main circuit breaker or ignition switch, check for loose connections and continuity.
5. Faulty system and or ignition relay, check for continuity.
6. Faulty ignition coil, ignition/electronic module.
7. Faulty 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. Fuel tank empty
11. Fuel tank contaminated with ethanol sludge.
12. Water or dirt in the fuel system, or clogged filter.
13. Restricted, blocked or kinked fuel line.
14. Faulty fuel pump.
15. Faulty pressure regulator.
16. Faulty or clogged fuel injectors.
17. Lean angle switch is faulty or needs adjustment.

To my knowledge, there are no onboard electrical/electronic components capable of shorting and blowing the fuse with out blowing any of the secondary fuse. The main fuse could possibly blow due to a short in the wiring or an exposed/frayed wire touching the body. The three most likely areas would be:

Hi and welcome to FixYa,
Your description indicates an electrical malfunction. Offhand, the jump start and charging is significant. This points to the bike's battery not charging. Suspects would be:

Your petcock could be bad try a pingel for a sure fix. Also check your vent on top of the gas tank, they become clogged a small piece of wire will clear it be sure you can **** air out of it. Unless your problem is electrical these may fix the problem.
