I started this elsewhere and I thought there was a project section, but unless one of corrects me, I'll post the project progress here.

The origins of this story, my son-in-law said I could have the bike if I could fix it, pay the insurance and registration fees and if he could ride it sometime. Sounds like good deal?

The bike had sat outside for a few years. I put in a new battery, but hitting the starter created some electrical sounds, no action, and lights out. I couldn't find any blown fuses, but after a 10-15 minute wait, it would light up again, I'd hit the starter and a repeat of the process. I removed tank, pulled the plugs and sprayed some WD 40 in the holes. Eventually, it turned over, but would not start.

The plugs had spark, but fuel was not getting to the engine. Fuel did not appear to flow from the petcock, so I ordered parts and rebuilt it. I then ordered kits for the carbs and took on that job. I had an awful time pulling the boots etc. Those of you who have tried this, know the frustration. I would go to the garage, frustrate myself for an hour and then go back a week later. While this was going on, I built a kayak, canoe, pram and rebuilt an old sailboat, putting in a new transom. I think it took me about 4 years to get the carbs off.

I recently cleaned the carbs and put them back together. Again with the frustration of the boots. I then discovered this sight, thank god! Hints from the group helped me get the carbs and boots back on. Thanks guys.

I put in a new batter today, hit the starter. Refer to paragraph 3. We will try again tomorrow.

About the boots to the airbox. I never did get the right side to seat correctly. I hope some sealant will work.

A pram is a small boat with a blunt bow, think john-boat. Mine was about 4ft x30 inches, with a sailing rig.

It's been about an hour and I still am not getting juice. I wonder what is tripping. All of the fuses are good. Starter relay?

Sounds like you have a short somewhere that is tripping a relay. The fun part is finding out where.  puzzled

The one time my carb boots were being especially stubborn I removed the air cleaner bolts and slid the thing further forward that normal. Once the boots are in place, you can take the pressure off the box and it will go in place.

I've replaced the starter solenoid once, but I might do it again. I don't think there is a short. I believe that the gunk in the engine has glued the pistons. The overload of the starter trips the solenoid.  I'm gonna pull the plugs tomorrow and spray various compounds into the cylinders to loosen them up.

The lights come on when I turn the switch, but go out when I hit the starter. Pulling the ground wire resets the solenoid.

As to the suggestion for the boots, I had already tried pulling the bolts and using ratcheting tie downs to pull the boots in. The right will not quite sit correctly, and the problem is on the inside, next to the backbone. difficult to get to.

Thanks for the suggestions. I'm always open to ideas.

I'm actually going to move this to the correct location. Follow the bread crumbs.
