Non start, fuel coming from exhaust

[Edward]

You can always connect a 9v battery to each injector independently or have them sent off for sonically cleaning which is a smart thing to do regardless. Mr. Injector does a fine service. Iridium plugs are good to have as well. Spray aerosol injector cleaner through them backwards from a fresh can. Then compressed air. Simple. Frankly sending them off is the proper method so they can be tested and visualized with a graph. Its all apart of the process, no worries. Step by step.

I've been following this thread and thought I would add my own experience with this issue.
The only time my bike would not start and was spitting fuel out the exhaust the culprit turned out to be a bad temp sensor.  It was telling the computer that the temp was extremely low and needed to dump fuel like crazy to overcome that situation.  I see you checked the resistance of the sensor, but could the problem lie in the wiring of that part of the system or the computer itself?

I rectified this issue so thought I would comment for closure.

I ensured all the points above were right.

Playing with the injector timing plate on the front of the engine, turning it clockwise led to the bike starting but revving high.

This was then rectified by resetting the TPS as it was not only in the wrong place it was also holding the idle open.

Both were tweaked for the best possible running and now the bike idles and starts fine.

To clarify my non firing injectors was down to the ECU being fried. The non starting after this point was spark timing and then TPS.

Thankyou everyone for all your inputs.
