Technical / Diagnostic help Request

Hey,

My 12' Street Triple is very unwell and I'm all out of ideas as to what might be wrong :-(
Bike only has just over 6,000 miles on it, and it lives in a garage.

Problem description:
Was running fine, then squirted it with a pressure washer (not smart I know #shame). Then it intermittently seemed to drop a cylinder, then dropped two, then all.
turns over fine, but doesn't even try and fire most of the time, occasionally sounds like one cylinder tries to fire but that's not enough to run on its own and then it reverts back to not firing.

Diagnostics I have done:

1. Fault Codes (dealerTool): None.
2. Spark test, All - I get a spark ( Coil lent against the frame with the plug in, turn over can see the spark and looks strong)
3. Fuel Delivery system - total disassembly (minus fuel pump/filter) and check all is good - Dealer tool reports injectors pulsing - all pinout tests - all report good ( Can't test if the injectors are blocked, but all 3 at the same time seems unlikely) - Used the pump test to empty the tank, and fuel quality and flow rate were good.
4. Air - I gots air.
5. Main ground point in the centre of the bike to the frame looked ok, but cleaned/decreased and tightened, same with battery terminals.
6. Used DealerTool to look at sensor values etc.
   1. Throttle position sensor = good
   2. MAP = good,
   3. Fall detection switch = good
   4. Side stand switch = good
   5. Clutch switch = Good
   6. Throttle balance shows good pressure and balanced
   7. O2 = Good
   8. Secondary Air Injection = Good
   9. Timing etc = good.
7. As the Injectors are pulsed, ASSUME that the crank position sensor is good
8. All Fuses are good, connections cleaned.

So, I'm out of ideas of what else it could be, and very much open to suggestions

I would check the crank position sensor a bit better. Also pull all electrical connections and spray with WD40 (displaces water). Reseal with dielectric grease. May only get the right scan at dealer.

I would be looking at the clutch lever switch and the side stand switch as they cut fuel supply to the injectors , the pump will still run but just circulate fuel back in to the tank .
Also the ignition switch is prone to water ingress and check fuses for corrosion and finaly as @Qship says WD40 the hell out of everything

I would bet some water is somewhere, unplug everything and wait `untill it dries out. A little air pressure may help.

Right -O chaps and Chapesses I have finally found out what issue was!

After a complete disassembly and reassembly, and a worn-out battery on my multimeter and some sore fingers later, it was...... water in the gas tank

Thanks for reporting back, and glad it is finally solved. I hope it gets back to being a great ride for you.

Ouch! After all all that - a simple solution. Glad you got ir solved. Thanks for reporting back. That may help someone else.

Most times its simple, and that leaves me out most of the time.

Was it from the pressure washer or just bad gas?

Hi Ozzy, I hope you don't mind me butting in - but I too have a 2012 Street Triple R that won't start! It cranks like crazy and I tested for spark, but won't start at all. I've been checking out as much as I can and now have the tank and fuel pump out, but not sure how to test it? I assume it's not getting fuel but before removing the injectors I thought I would test the fuel pump. I removed the hose from the tank bottom, hooked up another fuel hose into a bucket and turned on the ignition - it only dribbled fuel so I'm assumed the pump isn't pumping? I've read some of the notes above and wondering the best way to test it. Things like kick stand and clutch switch problems would effect the starter too right? So I eliminated those from suspicion. I also tested the CPS and it seems OK. Any ideas before I have to have it trucked over to a dealer :-(

Thank you all for any help!
