Died while going down the road

If it's 54 outside and the fan is not running because the cold air is passing through the radiator and the coolant is doing it's job. Then you come up on a red light and basically all of the sudden that 54 degree wind chill has somewhat stopped (because 54 degrees outside and going 50 mile per hour creates quite a wind chill) the engine will heat up, cause the thermostat to open allowing the fluid to flow through the system. Now the fan kicks in at 220 degrees and begins to cool everything back down or you start riding and the wind cools it back down again...........I hope this helps a little. My bike heats up quickly too especially after riding for awhile and then stopping at a red light. I flush my coolant system yearly before the winter. It's generally recommended every 2 years.Ref: https://www.gixxer.com/forums/80-06-07-gsx-r600-750/294175-rapid-heating-idle.html

Around 2000 was the first year for fuel injection for the GSXR 750. It really isn't a 'choke' in the true sense of the word. It's a device that causes a high idle similar to an 'enrichener circuit' to warm up the bike engine. There should be no damage to the engine by leaving it on for a short ride so I'm thinking there was an unlerlying issue with the bike that the previous owner left undisclosed.

Around 2003 that device was abandoned due to the advancement of technology in fuel injection and was no longer needed.

After typing this response I just noticed the original post date was in 2012 and I'm sure the bike has been either repaired, sold or crashed by now but maybe this answer will be helpful to someone else.....

I HAVE A 2005 GSXR 750 AND WHEN IM AT HIGH RPM THE BIKE SHUTS OFF. DOES THIS HAVE ANYTHING TO DO WITH THE FI CODE BLINKING? BUT THERE ARE DAYS WHEN IT RIDES FINE....WIERD

If it died while riding, this could be a broken wire, harness plug come loose, of faulty ignition switch, you will need to use a test light to check where the power is getting to.
The ignition switches switch a couple of different contacts when you turn the key, which could explain why the neutral lights come on and nothing else.

Seems you are running entirely off your battery.
Indications are a suspect lighting or source coil is shorting. Resistance test will show discrepancies. Data is available on-line, search technical/electrical manuals from Clymer or Haynes. An auto shop sells cheap multi-meters than you can use. It is a stationary test and will identify individual component problems. As rectifier/regulator, cdi box and wiring/switches/connections all have an effect. These test are outlined within these publications. Cheers (and don't get caught)

I just had the same problem 2004 gsxr 750. After massive troubleshooting and time I found out it was the gauge. So I then ebayed a gauge on ebay and bought on for 290 dollars. Speedo now works. I am just off on the actual speed, need to by a speedo healer.

I guess its the regulator/rectifier thats pushing too many volts down that wire. Try another unit after fixing the wire

i had this prob a nightmare my su 1000 done this then. after a few weeks,i would park up go for a cuppa , try to start it and nothing just clicking from the switch. i disconnected the immobiliser

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:

• voltage regulator (most likely);
• connectors to voltage regulator (likely). Check/clean corrosion/burnt marks;
• stator and/or the 3 wires coming from it (least likely).

Good luck and thank you for using FixYa.

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
