WideOpenThrottle Posted September 30, 2013 Report Share Posted September 30, 2013 I have a 2004 GSXR 1000 and I have a problem with it cutting out when it gets hot, acts like it is flooding out, all within a matter of a few seconds. It starts this after about three laps around 12,000 RPMs consistently. It isn't running hot. Never above 190 degrees. It has all new fuel system, new plugs, and has less than 3k miles on the motor! Any guesses as to what it could be? Quote Link to comment Share on other sites More sharing options...
dover Posted September 30, 2013 Report Share Posted September 30, 2013 Sounds like a loose ground to me, or spark blow out. Check your gaps and wiring. Quote Link to comment Share on other sites More sharing options...
Cordell Posted September 30, 2013 Report Share Posted September 30, 2013 Sounds electrical for sure, poor trigger, ground, ect. Does it have a tuner on it? That might be something I'd byass if possible. Quote Link to comment Share on other sites More sharing options...
WideOpenThrottle Posted October 1, 2013 Author Report Share Posted October 1, 2013 Thanks for the advice. Will put more grounds on it tomorrow and see how she fares. We were thinking maybe the ECU was getting hot and causing an issue. Anyone ever hear of that happening. We were getting hard up for.ideas.

WideOpenThrottle Posted October 1, 2013 Author Report Share Posted October 1, 2013 And it doesnt have a tuner or chip of any kind. It runs like a top until three laps in. Consistently Quote Link to comment Share on other sites More sharing options...
Cordell Posted October 1, 2013 Report Share Posted October 1, 2013 And it doesnt have a tuner or chip of any kind. It runs like a top until three laps in. Consistently Well heat is hard on electronics and you describe that type of issue perfectly. Bike runs fine, gets driven good and starts acting up when hot. An ignition coil comes to mind, or a tuner which is why I mentioned it. I'm no bike expert, but I would get it fucking up and start narrowing the issue down. Is it spark or fuel related? Things like that. Best of luck, hopefully you can find some more bike specific ideas. Quote Link to comment Share on other sites More sharing options...
1fast5gp Posted October 1, 2013 Report Share Posted October 1, 2013 if the plugs in the proper heat range and they are gapped correctly, I would think it could be your coil packs. Quote Link to comment Share on other sites More sharing options...

Any guesses as to what it could be? Do you have a wideband setup on it? I can't remember which way it goes but a misfire will show up differently than when combustion is correct. My instinct says rich because of the unburnt fuel but some reason I think it is supposed to be lean. Quote Link to comment Share on other sites More sharing options...
Bigfoot Posted October 9, 2013 Report Share Posted October 9, 2013 Rectifier/Regulator? Ive had them act like they are going out only when the bike is hot. Honda had a huge issue with them, not so much Suzuki. Quote Link to comment Share on other sites More sharing options...
