What did I do today.... I logged in to this site for the first time in about a decade... So I'll summarize. I now have three completeish XS650s. Acquired a survivor chop last week. Thing had been in a storage unit for at least 22 years. '72 engine. Solex BS38s. Good compression, transmission and clutch seem good. It has a Columbus (?) twisted front springer on it, sitting in a pretty raked-out frame of unknown origin. Has a single square stock center down tube / brace. I'll try to figure out how to post photos here. It was photobucket back in the day, and we all know how that turned out.

Anyhow, today I got carb kits ordered, new carb boots and new diaphragms as well, and a HHB CDI setup. Should have her waking the neighbor's dead cats by next week.

Did a little prep required to swap a TCI engine of unknown status into my '77 non-TCI bike. Made a test/start panel to test the starter motor, p/u coil, TCI box, solenoid and TCI-coil on the bench. Will be used eventually for an engine test-run stand. All bits test OK, including a spare coil.

Prepped a new sump plate, fixed torn pick-up filter screen and cleaned oil filter on the TCI engine.

One step at a time...

Ever since installing a @gggGary 8 plate clutch I have had a few self induced and phantom problems. Jetting was close but sometimes while riding everything seemed "off". I finally went one step up on the primary jets and the bike was magically transformed to "almost civilized" but that "off" feeling came back. Each time it seemed off the battery would be weak but a volt check indicated it was charging. I adjusted the regulator up twice, checked core and point gap. Same thing again but with a fresh charge the bike runs really nice. A check, again, of the alt output revealed it would stay at battery voltage then jump to 12.9-13.3 depending on revs 2500-3500. Having read in these forums warnings about stressing the alternator, I located the VR115 regulator I ordered 2-3 months ago and cludged up a mount. Now it seems to charge at 12.7-12.9 at idle and 13.4-13.6 at 3000 rpm. Time for a ride to see where the battery is after 20-40 miles.

And I came back from my ride at 11.8 v ! I will pull the @Jim checks of grounds, contacts, etc. I never had the battery out so that might be an issue.

Get the engine warmed up (hot), pull the brushes and check resistance on the rotor slip rings. Should be about 5Ω. When they get hot is when you'll see the insulation go to hell and resistance drop or go way high. Since it was charging OK starting out, that's a good possibility.

Thanks Jim I will do that. This is weird because the Ozarks rally was incident free and I was feeling confident. I will inspect/clean the ground and then make that check. Outer ring to ground? Or better yet, reference the tech section I should check.:D After I saw the 11.8v after the ride, I revved the motor a little, 2000-3000 rpm and voltage jumped to 13.1-13.4ish. Much of my ride was the 2500-3000 range but there were 10 minute stretches, 45 mph, of 3500 ish running. I hope I don't pull the battery and find a 2013 date stamp. That would be embarassing.
