1975 GL1000 Crank, No Start.

Postby Alex423D » Wed Oct 07, 2015 1:38 am



Hello I'm Alex. I just bought a 1975 GL1000 Goldwing as a progect. It will crank but will not start. I've checked the battery and it seems to be good, well over 12 volts. Also, because it cranks I asume it has spark.
With the air filter out I sprayed some starter fluid into the carbs and it sounded like it was starting or it did start as long as I kept adding started fluid. There are to hoses on the right side of the bike for fuel, one that goes from the carb and one has a clear plastic container with gas in it. I took the hose that goes from the carb off and turn the gas handle and fuel squirts out. I'm kinda stuck, I would appreciate any tips, thank you.

Hi Alex. Welcome.

Firstly, I would suggest making sure that all 4 plugs have a spark, simply because it's so easy to do and necessary for the engine to run.
However, the fact that you say the bike starts when starter fluid is sprayed, suggests that the carb jets are gummed up. With GL1000's, a thorough carb clean should be one of the first things to do when bringing the bike back to life. Search this forum for threads on the subject and look at Randakks Cycle Shack website for details on how to clean/rebuild the carbs properly.
How long has the bike been standing? How old is the fuel? Try loosening each float bowl drain screw to check if fuel is actually getting into the carbs and, if it is, try rigging up a fresh fuel supply to see what happens. My best guess is that the carbs will definitely need the aforementioned 'deep clean' to unplug the internal jets/passageways.
Don't give up on it though. They are fantastic bikes and you'll love it when it's back on the road.

Thank you, I appreciate the tips. Ill start as soon as I get home, I thought it was the carb I just dont have much experience with them. Ill do some research and get on it. Would you recommend taking it in and getting it professionally rebuilt?
Again, thank you very much.

I would always recommend having a go yourself first, so long as you have a basic knowledge of engines etc. These are quite straightforward bikes, although they do have a few quirks! Best advice- read lots and don't be afraid to ask questions. We're here to help each other keep these iconic bikes on the road.
With regards to the carbs, if you think they're clean inside, they're probably not!
Good luck.

That's what I'd recommend. From your reference of the fuel filter as a "clear plastic container with gas in it" and the petcock as "the gas handle" I foresee broken float posts, mangled emulsion tubes and stripped bowl threads if you tried to overhaul GL1000 carbs yourself. You already admitted you don't have carb experience and a set of old GL carbs are not the ones to learn on, in my opinion.

There are very fewbike shops with techs qqualified to touch those carbs these days. I suggest you want Randakks GL1000 video several times, like up to seven times. Then ask around about a vintage bike or car affectionato person to help.

Mike Nixon's book on GL1000 carbs is very good as well. Lots of helpful pictures.
