For what its worth, the GL runs so much stronger when both cylinders are working together. Steve 1982 GL500I    Report

There was still gas in the tank right. The loop just caused the fuel not to come all the way to the carbs. Simple solution is to eliminate the loop and walla you have gas again. Just trying to clarify you still had gas in the tank. 1978 Honda Cx500 Maggot 1979 Honda Cx500 Custom 1980 Cx500 Deluxe Buy HTTA Items Quick Reference Info    Report

I ran out of gas once on a six lane interstate in the far left passing lane with no pull off on that side. I was lucky as hell to be able to make my way all the way to the right while the bike was surging sucking up every last drop of gas. The thing that sucked is I actually had a gallon of gas in the tank but the reserve wasn't working. I could blow air into the tank through the fuel hose but none would come out.  Problems fixed now. Thank god. But I'm still going to carry my 33 ounce MSR bottle of gas. 1978 Honda Cx500 Maggot 1979 Honda Cx500 Custom 1980 Cx500 Deluxe Buy HTTA Items Quick Reference Info    Report

I used a very large filter from a auto-shop. - I looped it, - - It ran for a mile, then topped-out at 40 mph.- - - I sure wish that I had read more post, here, before I did that.  -  - - -     Hint, hint, BS  "In-line fuel-filter thread. - Please. For now, I'm sticking with the small 'cone-shaped air-stone' type filter. I have it as much  vertical as I can. That lasted 13 months, with a rusty tank. - (I have read that the right angle full-filters might be better). The metal screen filters do not work. There is always going to be an air-bubble in the 'GL'  filter  - - More-so after a long sit, "evaporation ;will happen, in a vented vacuum carb ". - - - After a 3- four day sit, I blow into the petcock drain tube. - "Yea, I know that it sounds weird". And can be misused, but it works; on these GLs. After 5, or more days sitting, I drain the carbs.  Hopefully, forehand. - - - But, sometimes after. - And charge a good battery after three weeks. It works for us. These bikes were designed to run, -  not sit! - -  (run it)! "The loop just caused the fuel not to come all the way to the carbs." Yea, I did this with a 1/2 a tank. (It only takes, an inch or two, over the bottom of the petcock. to mess it up, bad).   RustyTec ’81 GL500. Dallas Texas. RustyVape Electronic Cigarettes Local NE Dallas, Texas    Report

Just to be sure, you do know about the reserve setting on the petcock, right? Sounds to me you may have been on reserve at 150 miles with a gallon left. That is about the height of the "straw" in the tank that is designed to not let you run out of gas. (just checking) Wayne 1983 GL650 Silverwing Interstate WWW.fossilapostles.com    Report
