So I checked the points yesterday while holding the electric starter and both were opening and closing. I did the business card trick while cleaning with electric parts cleaner. I also measured with feeler gauges and I believe I did it properly. The .012 feeler gauge seemed to slip in with...

So I opened up the headlight and cleaned that connector that winged was referring to(the one I'm pointing to in the picture). Still no spark. A side note, I just noticed a connector that doesn't seem to have a male counterpart. It's located near the condenser near the two coils. Anyone...

Thanks Winged, away on vacation now but will be back to the drawing board when I'm home.

I am getting power to the coils but I'm getting a reading of 11.4. Would that be issue enough to cause a no spark? I'm losing power somewhere along the line here but is it substantial enough to produce this no spark issue? Could the lack of spark be related to an issue with the run/stop...

So the bike neither sparks nor E-start nor kick start. I was getting a 4 at both primary coils and 16ish at the secondarys. Next steps?

I have not tried looking for spark while kicking. Will do that, thanks.

I hold the start button, it's operating, and the pistons are going up and down. So I'm a novice with a multimeter and most things electronics. Will try my best and report back. Is there a 1975 wiring diagram in the tech section?

So put the battery in and got lights all over. The starter works and is trying to start the bike but it wouldn't turn over. Basically drained the brand new battery trying to get it to turn over. Charged the battery to full again and from there tested the spark plugs and spark plug caps by...

Carbs cleaned up to the best of my ability. 40 years of sitting didn't do them any favors. The insides were stained black for the most part. Wasn't able to remove the black stains from the slides as you can tell from the picture. Overall, everything cleaned up nicely. The RTV worked well on...

Carbs disassembled and soaking at the moment. Upon inspection one of the diaphragms had a hairline tear. I'm sure you guys are familiar with Mr. Miyagi on YouTube (another xs650 enthusiast). He uses a 3M weather stripping product right around minute 48 in this video. Anyone have...

The @Mailman delivers! Thank you. Going to study these pics next to my set tomorrow.

Carbs are pulled. Preparing to disassemble tomorrow. Before I do I have a few questions/concerns. First concern; While working the carbs out of the intake manifolds the two carbs separated. There is a rubber tube containing brass connectors that is the bridge between the two. As you...

Looks great winged. Gives me hope for my project.

Wow vinegar goes a long way!

Yeah I'm just going to try a 3 stage fuel tank restoration kit from AutoZone and hope for the best.

Finally back in my shop able to take pictures after 2 days of snow removal. Gas tank is pretty rusty. Savable? As you can see by the exhaust picture, I think most of the rest is sandpaperable with 150 grade. As you can see I attached a picture of two batteries; one being the old battery that...

Great, this definitely simplifies things. Thank you!

Along with new wiring harness do you guys think I should be putting a PMA type alternator and an aftermarket ignition system in?

Odometer is 20xxxish. It received another '75 replacement engine in '81by a motorcycle shop. I even have the receipt for that. Pretty wild.

Those look awesome Niels! I'll post some more close up pics later when I'm off my plow shift o_O. I was honestly planning a full restore originally and when I got it home yesterday I started to get a bit intimidated by a rusty inner tank, mouse chewed wires, etc. but everyone here is starting...
