Hahaha, crap. K, I'll check that today....my luck, it'll be on there completely opposite of this
....of course I got all excited during assembly and didn't even think of that.

Hey guys, still cruddy outside so went back into the rotor side to slap Jim's rebuild on and install a one piece clutch pushrod/bushing/ and another seal while I was there. interesting though....I noticed the sprocket nut backed off a tad in the 80ish miles I rode after changing that seal??? I originally torqued to 94ft lbs. So that's what I re-torqued to. The bent over tabs did their job in somewhat catching the nut. Just thought it was strange and if you guys have ever ran into that?
Yes. It's a thing. At least, it has been for me. When you get a leak, check that first.
Is that a new sprocket? Looks like a lot of side wear in 80 miles, how's your wheel alignment?
Loose sprockets happen fersher.
It's kinda fiddly getting that washer to stay correctly in the splines while tightening the nut.
Masking tape.
No Gary, that's the original front sprocket. I'm guessing it had a hard life from the p.o., wheel alignment is spot on now. Had a new reg/rec on the shelf, threw that at it too.....bad.....right out of the mikes box
. Connected old '80 known good one and it charges. Don't worry Jim, not for one second did I suspect your rotor was the problem

Darn, we coulda started another Mega-thread!Don't worry Jim, not for one second did I suspect your rotor was the problem
Finally got a test ride on the 81'. Wow, tapered steering bearings feel great! They were set a tad tight and seem to have settled nicely. Jim's rotor rebuild charged well too! Here's the plug chop results, curious as to your guys thoughts? I've been suspecting weak coil action on the right side for awhile (just judging from colors of exhaust pipes). The right plug is a little more black. For reference, during the carb rebuild I jumped up to 135 mains, 45 pilots, and idle screws are 3.5 turns out, they're syncd up and squeaky clean as well. Seems to run great, however I do suspect a possible vacuum leak as I seem to be chasing the idle adjustment a little bit, the carbs are coming off again soon to do new boots and probably throttle shaft seals as I didn't have those at the time of rebuild.
Plugs look "good enough" for now.
Change the boots and seals.... then revisit plug color would be how I'd proceed.

Don't recall if you're still running the factory TCI? If so a Honda MP08 coil is a nice upgrade.... a used one, not the cheap Chinese new ones out there on Ebay.
The TCI uses a single, dual output coil... firing both plugs at the same time. Because of that the spark jumps from the center to ground electrode on one side and opposite.... ground to center, on the other. You can swap the connectors going to the coil... orange (red/white?) and brown. Swapping them will swap sides on spark direction. You can try that to see if the dark color on the plug swaps sides.
Of course, like I said... it's best to get the carbs and boots sorted first.

holy moly those carbs look great!Pulled the carbs off again, checked floats, changed throttle shaft seals and re-sync'd. Test rode good, forgot the plug chop stuff on the bench.... always next weekend.

Finally got around to installing a new regulator today. Also, changed tach drive seal and o-ring, with cover in place. Wasn't as bad as I thought it would be. Greased and swapped out tach and speedo cables while I was at it.
