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.
