gas leak

Postby fishingrod » Fri May 30, 2014 11:18 am



Have 81 gl11oo, I have gas leaking from the bottom float bowls on both left side carbs. What can I do to stop this other than a carb rebuild. Right sides don't leak, my guess is that the float valves are stuck open due to bad gas left in tank over the winter. I knew that when I bought bike and thought it would be a 3 to 4 hundred dollar rebuild so I talked him into selling for 200 less, now I can't find anyone to do it for less that 700. I 'm probably going to have to bite the bullet for 700 but hopefully this forum can give me a better idea. Its worth a shot. Thanks

Stuck floats can be cleaned..pivot, seat or the needle itself..for a lot less than $700
One of the best re builders is Pistol Pete..$400 I think.

But I'd remove them have to anyway for a rebuild..and remove the float needle seats clean them up replace them and bench test..fairly easy..Or buy new needles and seats $20 each from Honda and just put them in..very easy..then check for float levels and that's it.

leave the carbs attached to the plenum and don't remove any of the jets if you are sure the only issue is the needles not sealing..and else thing else should be OK as you won't disturb anything else..sometimes fixing stuff causes other issues....

Thought I'd add he rebuilds them with Randakk's kit and tests them on his test engine..when you get them it's just install and ride.

Good info here http://www.oldwings.com/services.html
prices are up a bit

Thank you rbgerson for your reply, it was very helpful. Removed the carbs and found that the float bowl drain plugs on both left carbs where broken off so found some new used ones and than went through all float bowls and found needle valve on carb 3 was full of crap so I cleaned it and reinstalled, problem solved. Runs good, especially at highway speeds, is a little sluggish at idle and pops a little also at low engine rpm. I haven't put many miles on since cleaning the bowls but the idle has improved since start up with some quality gas and seafoam. Could this be that they are out of sync, if so where can a guy get a good vacuum gauge? Thanks again for your help

If you want to save a few bucks, you can build your own vacuum gauge out of a couple lengths of vinyl tubing and a board to fasten them to. Have a look at Cheap carb sync tool
