Don't die like this, DL1000!

I'm discouraged. My 05 (65ishK miles) just had her valve clearance adjusted (standard one exhaust out of spec). Then the charging system finally gave up on me and stranded me at work. I build up some money, buy the stuff, put a new Charging set in, buttoned her back up and took her for a shakedown run.

MAN it was great. I hadn't realized how much the electrics were crapping me out. Hasn't run that good in a while.

Saturday morning I pile on and head out to the Experienced Rider Course where I will enjoy riding my strom again. I zip up the highway and onto the offramp and... DISASTER. Strom dies at the light. NONONONO. I get it to start up, kinda, and idle, shittily, by turning the idle up, but try to get it to pull me along and BLUH down she goes.

That day I could get it to start a little with throttle on, but then it'd vroooom DIE. Poking around I discovered that the blanking caps on my extender hoses had cracked and fallen apart. I replaced those feeling dumb but observant aaaaand... Nothing. It'll turn over and starter spins happily but doesn't catch and run.

Got it at home. Here's what I know, I need help:
*Plugs were black and wet. Reek of gas. Both look about the same.
*Put a new plug in the boot and it has spark. Coils in spec for resistance.
*New air filter for good measure. It was grungy.
*Fuel pump gives me 350ml on the money with three turns of the key. Fresh inline filter (HP filter is bypassed ages ago) and checked hose for flow (it flows)
*WFO throttle and starter give a noticable "bupbupbup" that isn't present otherwise.

Odd things:
*I put fresh plugs in and it started to idle high, popped, and died. Nothing doing after that.
*Left plugs out, rags in holes, and let the cylinders air out while at work. Idled a little, popped and died, with a burny smell on the next spin.
*When I popped the hose off the bottom of the pump, it sprayed so hard it got me in the eye. I don't remember it having had that much pressure before.

I'm losing my mind here. I'd be spark suspicious or compression suspicious but both cylinders look the same on the plugs, which I wouldn't expect from single cylinder catastrophe.

I'm getting good at taking the tank on and off though, so there's that? Mayday, Stromtroopers!

Could still be the fuel pump, if the vanes are worn . It must put out pressure as well as volume. If the plugs are wet with fuel, and you have spark, it could be that raw fuel is being dumped in the intake. There must be high pressure at the injectors for a good spray of fuel/air mixture. The pressure when you pull the line is misleading, need a gauge to measure.

Not madness. It'd account for the kinda start when some fuel has a chance to aerosolize. Just ordered the E8229 fuel pump from rockauto that I left in my cart in case the volume test failed. Apart from the fuel rail at this point it's the only piece common to both cylinders. Here's hoping!

If you have spark and that much raw gas, I am not thinking it is a fuel problem.

Spark is good, but only when it arrives at the correct time. While I want to point to the throttle position sensor, I have never seen one completely fail where it won't eventually start. But don't rule it out. You mention a charging system. Is there a chance your crankshaft position sensor might have come loose? Or maybe a wire from it has gotten pinched in the cover or elsewhere?

I also think that it is electrical so long as you can guarantee that you do not have polluted fuel in the tank.

Popping or backfiring is usually associated with electrical issues. Fuel pressure or supply issues usually cause the engine just to run down below its idle speed and fade to a halt - like when you run out of fuel.

Some more info could help.
How long since (the shop?) adjusted the valves.
How far did you travel on the motorway without issues, before pulling up at some lights and the bike dying?
Does your bike fail EVERY time you go for a ride? If not what rides have been O.K.and under what conditions does it fail? Are there any similarities.
Could the fuel have somehow become contaminated - perhaps with water?
Are you sure that all the hoses have been correctly re-connected to the fuel tank?
What exactly is "a new charging set"?

There is no such thing as too much information.
Can we assume that you had to trailer your bike home from the lights and that it has not started since?

Check that the throttle bodies didn't pop out of their boots.

In Orderish asked:

Crank sensor is brand spanking new and came with the new stator.

I wrench myself. The Stator was history and the R/R consequently suspect and for good measure all my rotor magnets had migrated to one side. I JB weld positioned the magnets as others have, replaced the stator/crank sensor and closed it up. Now you've got me paranoid I did something dumb with it, but there's a rubber grommet thing that creates a clean exit from the cover so I thiiiink that's ok. It's worth a look.

Valves were done like 4 months ago by me. It ran well for a month until the charging system shit itself for good in early May and the bike spent a weekend plugged into the wall at work. :|

Between exits it's something like 5-6 miles give or take. It was on the first gas warning blink when it died, which makes me wonder if I have some sludge built up that got in while it sat waiting for charging parts. Seems like 2-3 months isn't long enough but since I'm likely to have the pump out, I'll drain it all off and give it a gander. The 350ml that came out in my volume test looked alright.

Since dying the Bike fails EVERY time. I had to trailer it home, thankfully my co-coach that day has a trailer and owes me some bike rescues.

The bike is now a large navigation hazard in my garage. It'll crank just fine, and occasionally after sitting a bit will catch and run long enough to rev to 4kish then gradually die off. That gradual die off and the TOTAL lack of fuel stench in the garage despite copious useless cranking is one of the things that makes me fuel-suspicious.

Yeah, contamination was a concern and isn't off the table but as mentioned what I drained seemed ok and ran ok when I put it in my favorite test engine: The lawnmower that won't die.

New Charging set means a totally new stator and R/R unit (and gasket and Crank sensor secondarily).

The Boot unbooting from the throttle body is a good idea but A.) I've had that happen a couple times and it didn't present like this. B.) I checked anyway because you're right, happens a lot.

Thus far the theories that my Strom-sense likes best are the pump being weak or that I've cocked up the Crank position sensor somehow. I prefer the first because this feels too analog for a sensor failure.

In other news, my wife just presented me with a handfull of squeaky clean DL1000 fairing screws and plastic pushrivets because I left them in the cargo pocket of my shorts.

Three things are needed for an engine to run. Spark, compression, and fuel. Fuel is good. Compression is good. Spark is good. UNTIL you do not have spark or fuel. My money is on spark.

After it dies check to see if you still have spark. There may be a ground that occurs after the something warms up. If it dies and still has spark it has to be a fuel issue. If it does not have spark after running you have a heat related ground or a heat induced lack of continuity.

What is WFO?

It may be a flaky Fuel Pump Relay which also powers the Fuel Injectors. Throwing parts at a bike that won't run can get expensive real fast so you need to test it but I don't know if there is a test procedure in the service manual for the relay. At the very least pull it and clean the connectors and (gently) bang it around a bit to loosen it up if the latch inside is sticking and not fully engaging. Also, if you examine the wiring diagram maybe there is a way to bypass it to get power to the pump/injectors as a test. Be careful what wires you jump as the relay is controlled by the ECU and you don't want to fry that.
