This is a first for me. my bike has been running well no issues or problems, but today after running a few errands I got on her to head home, cranked her over and she started right up but there was a weird noise sounded like a piston was scraping or something so I shut her down with the key ASAP..but the starter was engaged and running, hit the kill switch..starter still running..so I got of the bike and in my best wrencher style I kicked the starter..the bike popped forward, I guess I left it in gear on the initial shut down..but that stopped it. My kicking it seemed to engage the starter clutch and that with the engine in gear stop it..I guess.
So I tried her again fired right up and I drove off just like nothing happened.
Ok guys you CAN NOT take apart the solenoid and flip the plate for some of the solenoids..the one I just trashed is from an 81 GL1100..maybe not be OEM hard to tell..Anyway this one is not screwed together it has three depression clips on the top edge of the bottom casing which can be pried out and it does come lose but you can't pull the bottom off w/o breaking the small wires that go to the coil and are solder into the top contacts points.
And the plate, a split plate at that, in this one didn't just fall out and I couldn't even pry it loose it also had a button in the middle that was spring loaded and kept the contact piston from making contact.
Note if you heat up the solder joints on top and pull at the same time you could pull this one apart w/o breaking anything. But I am not sure what that would get you..you could clean the plate I guess and then try to slide those tiny wires back up into the holes and re-solder them..but holding it all in place against the spring and then trying to push the three depression clips/slots back in would be a challenge..you need four hands...
When they start sticking it's usually burning of contacts that causes it. Not worth trying to do anything with them, if you can take one apart and file the contacts they will burn right away again because the hard coating is gone.
