79 GL 1000

Postby Guglielmo » Sun Jun 26, 2016 9:30 am



hello
I recently purchased a 79 GL 1000 for the most part it is very nice and all original , was told these bikes are cold blooded, and seems to be true, takes at least 2 min to get it to run half way acceptable, the usual items are all good, plugs , carbs, etc,,, and when warm seems to be alright, with an idle of around 1300
any advantage to updating the carburetor to a single carb, ?
at the moment it has all the original equipment, and I kind of like it that way. Also my throttle is what I would consider tight to roll. I already purchased the push pull cables, to replace them. Seems a little involved to do, any advice, or help would be appreciated, ( I do have a technical background, so not a complete idiot,,lol)
any thoughts? thanks in advance

They're definitely are a cold natured beast in original stock form, they like a little choke. They are not like modern fuel injected bikes that fire instantly then just let out the clutch and go.

Improvements can be made.
This is secondhand infomation but many rave about the combo of a pricey C5 ignition system coupled with single carb setup. I researched it and found that many have a lot of trouble sourcing the "right" single carb. Even then it requires a lot of tinkering and tuning to get and keep it dialed in.


With all things considered, I upgraded to an more affordable Dyna S full monty electronic ignition system and a quality Randakk's carb rebuild.

This helped cold starts but it still likes a little choke nursing for first minute of so. After that it's golden.

thanks, I recently found out that mine has the electronic pickup , which I assume is where the points used to be,,lol. I took the cover off to repaint it, and noticed. My bike starts right up , but most def stumbles and pops for about 45 secs or longer, but ultimately it runs decent. Im probably going to leave it alone as it is an inherent problem. I allow my machines to have a personality. I think it makes it more interesting,,, I heard that a quality carb rebuild is a good thing, and down the road I may just go ahead and do that, but the previous owner said they were done, by I believe who you mentioned, but of course I cant be sure.

Nice bike. 1300 rpm is too high for the bike It should idle at around 950 rpm after warm up.

Thats true, I totally missed that detail.
Honda service manual specs normal idle speed at 950-1050 rpm

Ill take care of the idle , I thought that was to high
this evening I replaced both throttle cables, what a joy that was. I noticed one of them was off, (the push cable) and was just working on the pull cable, I didnt want to get stuck like I did about 5 years ago with my other Goldwing,,
my throttle is a little tight/stiff, is this normal,? I routed the cables with the smoothest curves I could, just seems a little tight, is this normal??

No it's not normal. I put new push and pull throttle cables on mine too, Correct routing is critical to smooth operation and that proper throttle return snap back.

Replacing cables, I usually thread the new one through at the same time and drawing it through with the old one to be sure about the exact routing. The throttle should work very easily. Maybe check the throttle rotation at the handle and at the carb too with the cables unattached?
My 77 needs a full choke to start when cold, even on hot days and then partial choke until warm, has since new. You might try some seafoam or startron before rebuilding the carbs. It might be my imagination but I think an occasional ounce of Marvel Mystery Oil helps the carbs too?
