Thought we had our bike running and ready to go. Went and had carbs synced hoping it would improve the gas mileage. well it didnt. Now when we start from a complete stop like a stop sign or signal, the bike is doing a "glugging" (what I like to call it). It hesitates and acts like it wants to stall out when starting.



Any suggestions on where to start?

Flooding carbs..bad float needle, leaking o rings etc. floats set wrong..note the GL's like a higher rev start..or they will lug...

Take the air filter off and look into the plenum ..any gas sitting in there??? shouldn't be

This did it before we had the carbs synced as well. also our gas mileage is TERRIBLE lucky to get 80 miles on a tank before we have to kick to reserve.

You might want to replace your air cutoff valve also.

There is something seriously wrong with a 1000 that will only go 80 miles on a tank of gas.

You say you got your carbs synchd, How long since they were rebuilt completely? What do your plugs look like? exhaust pipes full of black soot? Still running points? How long since they were inspected/ adjusted/ replaced? same for timing? Is it even firing on all 4?

Sorry gifusion but the Air cut off valve has exactly zero to do with what he is describing. The Air cut off valve's ONLY purpose is to enrich the idle circuits during periods of high Vacuum and low fuel flow (ie. decelerating) to prevent backfiring. It has nothing to do with fuel economy or normal idle or acceleration.

the carbs were synced like 2 weeks ago, carbs rebuilt...couldnt tell ya, we talked with a friend today and hesaid he could take them off, clean and rebuild them for us. Plugs we put in new about a month ago, and the exhaust does on the right side put out someblack crap, noticed when it was idling sitting with the pipe on the curb. But its on the right side, left doesnt do it at all. Timing belt I couldnt tell ya either when it was done, and yes it is firing on all 4.

Will try the carb rebuild and cleaning and hopefully it gets better, hell it cant get any worse than 80 miles to a TANK OFGAS.

The gl1000 has main jets that are held in the carb body by O rings and pressure from the float chamber cover. They are not threaded into the carbs as in most motorcycles. If those O rings have deteriorated, as they did on my previous bike, the gas gets sucked around the main jet as well as thru it, and your mileage pretty well hits the gutter. If this is the case, just replace the O rings, 1 per jet. You may have to shop around to find the right size rings, cause I don't think Honda stocks them anymore.

When my Carbs were bad out of Synch and I would take off with moderate throttle and when I got up to speed and dropped the hammer it would stumble until I backed off some of the throttle and it caught up.

If you get scared half to death twice, would you be dead?
