Take it out and look, maybe it's worn brushes, maybe worn bearings, dunno what else.
Still it may be a problem with wiring to the starter
At least it's not an ignition problem, starters are easy.
If you need a starter, I may have an extra.

Returning Visitors
If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.
If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

I'll take a look at it and see what I can see. What you are saying is that this isn't a definite answer about what part of my system is bad, but confirmation that the ignition system is functional?
The ignition is fine, something to do with the starter circuit has a problem, not sure just what.

Took the starter apart. Didn't see much out of the ordinary. I cleaned up the brushes a bit, and put it all back together. Mounted it back on the bike, and connected the battery. Guess what?
Spark on plug, with plugs mounted and full compression on the cylinders. ??
I may never understand what I just witnessed, and I probably wouldn't believe it if I hadn't seen it myself. Touchy little scooter.....
We'll see if it holds up, and I will try it again tomorrow. Maybe I've just been in the garage too long...Hope not.

77 GS400 Right Pipe Cold
77 GS400 Right Pipe Cold
The bike was sitting for 31+ years and I have rebuilt and repaired some small problems.
1. cleaned repaired gas tank. coated inside with Kreem.
2. Fixed petcock and remounted on tank
3. Replaced seals and replaced fork oil
4. New tires
5. Cleaned carbs, cleaned carbs and then cleaned carbs again.
Bike has been running on both cylinders.
Today when I tried to start the bike it was very hard to start. could not keep running. Finally I was able to get it running, but the Right cylinder is not firing. I took the plug out and it only sparks when it is not contacting the head. If I place it on the head or ground it it stops sparking. when it does spark it sparks to the frame and across the gap at the same time.
I am at a loss
