    Strange…
    “pull over, kill bike, pop gas cap, bike doesn’t have enough power to start no choke, sounds like nearly dead battery!! Choke on start right away completely normal idle in nuetral

    take off and symptoms remain, but able to limp home.​“

    sounds like main jets could be clogged somehow….so it starts right up with “choke” and let’s you limp home. But why does it recover after a nap?
    can you drop a fuel bowl and see if any junk is visible …like floaters!

      Think he said running fine while at hwy speed for appx. half hr., starts messing up when exiting hwy. and is going at lower speed. Wondering if keep hwy. speed for another half hr. would it keep doing good or start messing up there also?

        Yeah that is correct

        I have NO issues from a cold start, about 30 miles of hwy riding (85 mph avg)

        it is not until after exiting the highway and slowing to about 55 that my problems occur. Which is why I think heat is the culprit. Slowing to get much less cooling with the bike at its hottest point.

        I’m going to try and install a voltmeter on the output of the stator and see if the lack of air after riding for so long is making the stator put out less voltage so the bike is just struggling in general. The battery still has enough charge to crank but that makes sense because it’s been charging for 30 miles. However, once I got home and turned the bike off, I immediately started it back up in neutral and measured battery voltage go from 12.3 to 12.9 and then continue to climb as normally. So that might put my theory in the dirt.

        when I get the time I’ll pull a float bowl and see if there’s a bunch of gunk just to rule it out. I’ll probably rebuild the gas cap too even though it doesn’t seem to be causing a vacuum at all.

        the only way I can really think of to see what the stator is putting out after a long ride is to have a voltmeter installed so I’ll just have to figure that one out.

          What is your oil temp gauge telling you?

            How about pulling a couple of spark plugs when acting up?
            If its fueling issue plugs will be white.
            If voltage issue plugs will be dark.

              My temp gauge is actually not currently working, however when it was working I have seen it approach 300 but not go past.

              plan on installing an oil cooler soon but can’t afford it at the moment

                I had similar readings my first summer on my 11EZ. Then I installed a cooler from an '84 1150 and never saw it go past 210. My 'thermostat' is a piece of cardboard twist tied on in winter.

                BTW, the 11E was designed with a cooler in mind but not supplied. No need to run lines over or around the engine, it's plug and play. However, you will need to modify the filter cover or replace it with an 1150 cover.

                  Okay new update, same symptoms but now the bike does not need to be hot. it still starts and runs fine in neutral but in any gear symptoms are present. really feels like intermittent firing on some cylinders. gunna start with coils/plug wires and see if those check out.

                  side note still going to install oil cooler as that may have caused whatever is having an issue to go bad

                    UPDATE FIXED:

                    went to pull everything apart to start troubleshooting and found the orange/white wire going to the 2/3 coil was broken and barely hanging on.

                    went through and replaced all coil connections/soldered/reconnected and shes back to running smooth as ever. still going to get an oil cooler installed, but problem is fixed for now!
