Only 25MPG

Post by glk17l »

Last fall I rebuilt the carbs on my 1993 GL1500. It had a coolant leak in the manifold, and the dreaded "idle surge". I fixed the leak and the collapsed vacuum hose, rebuilt the carbs, as long as the were out, even though they really didn't need it. I am now getting only about 25 MPG. Plugs and wires are OK. Any suggestions?

Does it idle steady at 850-900 rpm, , , it there any "stumble" off the line at stops?? Do you have to leave the choke on a lot? What was your gas mileage before this work? Are you on the throttle too often, best to keep "in-town" riding close to 2k rpm's if possible. I'm going to assume you'd notice/smell dripping or puddling gas.
