No fuel feed when trying to start

Post by chief771 » Wed Sep 12, 2018 11:51 pm



My gl1100 is being stubborn. I could crank on it all day and it wont start
If I dump fuel in the plenum it starts immediately. The choke is working but it is very stiff. Any ideas?!?!'

First question - how long have you owned it?
Second question - is there a maintenance history?
Third question - have you recently done any maintenance on it?
Fourth question - is there a good flow of fuel from the tank?
Fifth question - disconnect the fuel line to the carbs - does it pump fuel when cranking?

Any answers help diagnose -
Recent air filter or fuel filter change?

I have owned the bike for about 2 months. It had the carbs off and they were partially disassembled. I got new carb lots and rebuilt the carbs after they were boiled out. It does pump fuel when running but not when I am turning over the engine. A weak fuel pump maybe? The bike has not been running for several years. I did clean out the tank and removed the rust with a vinegar soak. The tank is nice and clean now and the pickups are clean . I put on a new fuel filter as well and changed all fluids. Once it is running it stays running. Ideas? Thank you for your reply!!!!

You need to check the fuel pump output to determine if it is actually working.

Doesn't make any sense except the pump turns slower on start up so if a weak pump less fuel....need a good battery..should be 15oz. at 3,000 rpm per minute..

After checking further, it seems when I pull out the choke cable it does not close the butterfly's in the carb. Is the choke adjustible?

There aren't any choke butterflies, it's actually not a "choke" in the normal sense, it's a "Fuel Enricher", opens up another fuel passage adding more fuel to the normal mix.

Thank you for the information. I appreciate it. Now I am really confused. Still trying to figure out the no fuel when trying to start it issue.

OK.... To clear the confusion there are choke butterflys. They can be seen with a mirror in the plenum looking through the screens. There is enough travel in the choke knob to fully actuate the choke butterflys. If it is stiff it could be the friction adjustment..... check this post...

Also disconnect the cable at the carbs and check the cable for freedom of movement. With the cable disconnected work the linkage by hand and verify that the butterflys are closing and fully opening.

Best of luck !!!

Thank you! I will get on that. I know when I pull out the choke it wont stay out and I watched the choke butterfly's and they do not close or move. I will check the cable and the friction adjustment. I really appreciate the help!!!

It looks like the choke cable is missing a part up by the pull end. Good news is I rode this bike for the first time today! From a goldwing in parts and not running to something i can drive now (after some more maintenance anyway). I dont want to sound egotistical but i am so darn proud of this accomplishment! Still have a few bugs to sort out but it's running and driving!! Thank you for all the help I received on here. You all are class A!

Hello all,
Still cant get the choke to work. It seems like I cant pull the cable out far enough to open the butterfly valves or I should say to close them. The bike starts great if i dump gas in the plenum and it stays running. This choke has got me stumped.. it does run and runs well! Getting closer to having it on the road.!!!
