I guess the resistance was good so I left it at that, I have often dreamt of sticking some nice shiny coils on it..š Worth lifting those boots and seeing what is underneath. Mine was not only that corroded, but the metal connector had broken in two. Have I asked you, lately, what relay you're running in Position #5?

Ā Ā Ā Ah, yeah, I remember now.Ā Running (even a good quality) 20 amp relay in a circuit pulling 22.5 amps can become an issue.Ā The G8HE OMRON is 35 amps NO, IIRC. I realize you're looking for something specific to the left cylinder, but a general problem with the Fuel Injection/Ignition system could be suspect as well.Ā Perhaps just swapping Rely #5 for #4 (the ECU real is pretty understressed) is worth a try and easy. Also, there are some nefarious spade connectors beneath the fuse block that feed the FI/Ignition through fuses #1 and #2: (The fuse block will just pry up out of the rubber mounts without messing with the fasteners.) 1
Grim Posted July 10, 2021 Author Posted July 10, 2021 Is this the code for the Omrons? G8HE-1C7T-R1-DC12 It seems they are on eBay now, they were not available last year when I looked. 1

po18guy Posted July 11, 2021 Posted July 11, 2021 The sad question is whether a Chrysler part will make a Guzzi more reliable... EDIT: OK, look at this: Omron-labelled relays from China marked "MADE IN USA" eBay item 123718429330 Ā Therefore, disregard the above. Ā

Hard to believe. High Current Relays I'll go out on a limb and call this legitimate. I spent time on Omron's website, they do make these but you can only have them if you're an OEM automotive concern- probably at least a tier 1 supplier. So if I was that and could order them, I would, since they have a purchasing requirement but no apparent limitation on subsequent usage. They probably have a minimum order quantity of 500 or something. Oh and West Bloomfield is in the heart of Mopar territory. one last point, it's not 5/$30, it's *each*. bleah
Grim Posted July 11, 2021 Author Posted July 11, 2021 Just a heads up.Ā Ā Do not use a locknut on your adjustment rod....š So I put this locknut on last time because I didn't trust the plastic nut not to move, but I just got everything in sync, left the bit running and as I held the plastic but in place and tightened my little locknut, I watched the sync go off by one vacuum inch. I guess it must squeez the nylon washer and pull the rod through a touch. Jeez. Ā I did go over the intake rubbers again and do the valves yet again (using my tiny German 3.5mm spanner). Well even with everything synced I need air screws out half a turn to make it idle with Meinhof's map, I didn't use the wacky sounding valve clearances though .003 for both?! My idle still ends up at about 590mv. But, the left is not missing, which is a win I'm my book! 2
docc Posted July 11, 2021 Posted July 11, 2021 True the "Dave Richardson" Lock Nut makes the synch knob a little more fiddly. It's much like holding the valve adjustment while cinching that lock nut. I do it while watching the balance tool to make sure it doesn't change. There is probably nothing wrong with using a little air bypass to get your outcome. Sounds like a success to me! And you are not the first to express some concern over the unusually loose valve lash listed . . . 1

Works fine in my case - but the ECU has an unreadable sticker over theĀ OEM label, so was probably re-flashed, but how or by whom I cannot say.
