    So I have a compression update. I started on right side, took out plug, screwed in compression tester, turned on key and kill switch, opened throttle and turned over until compression reading stabilized. Took 2 readings on both sides:

    Short story, both are 120-ish psi, which I believe is ok. Can someone please confirm that this is adequate or should I be seeing something higher than this?

    Given that this looked ok, I’m going to skip a leak down test unless I hear otherwise.

    I’m likely going to move into fuel tank next to change filter and check interior tank fuel lines.

    Coil bad? I.e. sparks in open air, but not under compression?

    Possibly; I’ll tackle that after checking fuel system inside tank

    Will the bike run on starting fluid?

    Did you check the side stand switch?
    At the switch there are three wires, white, brown and red. The red wire connects to a brown/white where the switch harness plugs into the bigger harness. This red wire should have either zero volts (if the side stand is up) or less than 1 volt (if the side stand is down and the trans is in neutral).
    If the side stand is down and the trans is NOT in neutral there should be a higher voltage on the red wire. Probably around 12 volts.

    Considering the elevation in Spokane is 1800 ft there is a correction factor for the lowish compression reading you are finding:

    http://kawtriple.com/mraxl/tips/compression_test.htm

    Cold engine and cheap HF gauge may also contribute to the lowish reading.

    In any case....bike should still run even with lowish compression so not the problem.Time to check fuel pressure as the pump or regulator may be weak.And pull the injectors and send them out for a cleaning/flow & balance test.

    Fuel injection 101? Check fuel pressure with a gauge.

    Where do I actually check these voltages?

    Nice! I’m actually in Bozeman at around 5500’, so a 120 psi reading is actually about right. Thanks for the link! That’s exactly what I was looking for.

    My gut is telling me fuel. I’ll tear into the fuel system tomorrow.

    I’ll have to pick some up next time I’m in town. Don’t have any here

    Possibly; how might one test that?

    As a start I would check them at the connector on the side stand switch cable while it is plugged in to the main system with the ignition on of course. You may have to insert a pin or wire into the back side of the connector to get a reading.
    If they aren't correct you can use a jumper wire to short the red wire to ground and see if the bike will start. Or unplug the SS switch connector and short the pin on the brown/white that the red wire plugs into to ground..

    If it fires with starting fluid (buy the good stuff without oil) then you know it’s a fuel delivery problem.
    My wires were going south close to engine heat.

    ...and I would just shoot it into the snorkel?

    I'd like to try this. Where would I shoot the starting fluid? Into the snorkel?

    You can go into the snorkel but it is more effective to go as close to the throttle bodies as possible.

    Victory!!! It was a fuel line in the tank that had come off (end of fuel filter back to pump). I swapped the filter while I was in there and it fired right up. Whoa that feels good. Test ride tomorrow.

    I WOULD LIKE TO THANK EVERYONE THAT HELPED ME TROUBLESHOOTING THIS—ESPECIALLY THOSE OF YOU THAT HELPED ME FROM THE SIDE OF THE ROAD. YOU ALL ARE WHAT MAKE ADV SO GREAT. I APPRECIATE YOU ALL.

    Congratulations on the quick diagnosis! It could have been much worse.

    Regarding weak coil: I think you look for a weak thin spark. Of course for that you need to know what a good spark looks like; maybe check next time you check your spark plugs. A good spark is like a mm wide, which is about as wide as long assuming a 0.8mm gap.

    From your original post looks like them internal lines were new?New as in the proper submersible fuel lines spec: SAE 30R10 ????

    Rather common a loose fuel line after previous work inside the tank.I haven't seen a "pop off" for a while.But at my yearly milleage I do replace the filter every year and once everything back together I verify the integrity of the fuel system with the fuel pressure gauge.

    And yes I had to go back in once to tighten up a line after finding a faster than it should be pressure bleed down.My K and same as the Rs retains a lot of its fuel pressure overnight or longer so if not time to either retighten the lines or look for leaky fuel injectors.
