Re: Died while going down the road
If you get power to the injectors it's not the ECU.Did you check for spark on the spark plugs when you renewed them?Disconnect the fuel,take them out,plug them on their cap, ground their body on the engine and crank it to see that every one is working properly.Also check the kill switch for proper "on-off" function and the kick stand's switch too.

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.....
First impression was why would anyone rev their motorcycle to 9 grand in neutral? I could see if you were in gear clutch pulled and ready for a "drag" or Race Start but in neutral?
Anyway I can't hear it so if the sound is like it hits 9k and starts popping then two things either an over rev limiter which I doubtr because the engine red lines at 13,500 OR you have a set of spark plugs breaking down under load
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.
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
