I'm a long time browser of this site, but now a first time user.
I have been resurrecting this low mileage (23,000 mi.) SP for about 2 years. Ran fine when I brought it home and put on 800 miles over the next year or so. Last fall the engine stopped for no obvious reason less than a mile from home. Inspection turned up lots of rust in the tank. I had the tank cleaned and coated by a local shop; replaced all fuel lines, cleaned pet cocks and rebuilt the carbs. Also, during the last year replaced plug wires, plugs, starter and other unrelated items. Cranked up the bike this past week and sorted out the recently rebuilt carbs; idles and seems to run fine. HOWEVER - it runs even and strong for less than a mile and then just quits, like it ran out of gas. Let it sit for awhile, it will crank up and go, but less distance.
Since I have been working this issue since last fall, professionals have suggested items such as proper gas cap, ensure a vented one is in use, etc. All suggestions have been tried, yet I have not identified the problem.
Could the problem be something other than fuel? The bike came with the common electronic ignition upgrade installed.
I'm at a loss for new ideasl
