I rode for about 45min, stopped for about 15min, and when I started back up, turn, stop, then the GD VINERROR again. Mind you, when I started it cold before the ride (after sitting overnight) it fired right up, fast as before.

A little poking around the internet warns of heat soaking the starter making it less efficient? Is that really a thing?

Its getting pretty annoying now. Do I need a f'n car battery to get this to start reliably?

Three times now, I have stopped for gas after riding between 30-90 minutes straight. I get gas, and bam... half crank, stop, and VINERR pops up. I let off the start switch, and try again, it fires right up. Because it starts on the second try, I too was wondering of this is an ACR issue. I don't have a PV, so I will have to listen for the "clicks".


EDIT: I went back and re-read a few posts here, and in theory, the ACRs seem very logical. I will admit, HD motors are very new to me, but the fact that I get a half crank, then stop... Then try again with no issue, that really seems like the ACRs. My question is, will the ACRs open after the first stall? Just to put it out there, I have not turned the ignition switch off when this happens, just let off the starter switch, then hit it again.

I don't know enough about how the compensator works to speak with any kind of authority, but if it works the way I think it does, I think it boils there's a cam and a ramp on the sprocket. My theory is that when it hard starts like that it's at or near the top of the compression stroke and near the break over point on the ramp, which causes just enough resistance that the starter can't over come it and it kicks back.

Again, I could be completely and totally effed up. But maybe not.
