76 GL1000 Issues, Questions, Upgrades

Post by 76GL1000LTD » Sun Mar 29, 2020 9:46 pm



Hi all,

Figured I will create another thread related to issues that my bike has apart from smoke. As well as any questions or upgrades I can think of.

Here are the issues that I would want to address:
1. Throttle is a bit sticky, doesn't return to neutral position easily. What can be done? Cable replacement, lubrication, etc? On the GS1000 that I had, I replaced throttle tube with later years Yamaha R1 tube to improve response, could this mod work for GL1000 as well?
2. Horn doesn't work. Not sure which part is broken, but when I press the button nothing happens.
3. Rust in the fuel tank. Either clean it out somehow or replace (finding replacement is probably next to impossible?). Looks like the tank has been repainted on the outside, paint is relatively fresh.
4. Noticed a cracked hose on the left hand side underneath fuel tank. What does it do and how important is it? (Will attach picture)
5. Another little issue is tachometer gauge slightly out of place. It seems to come out a bit from the rubber surround, unlike speedometer that is still in place. And in general gauges with the center lights are a bit shifted to the left (minor gripe). I'll try to attach picture of what I'm talking about, don't know if anything can be done or I should just accept that it's an old bike so it won't be perfect.

Question: What is a good repair manual to buy? I found two online, one is Clymer the other one is Haynes, which one is better?
Also, I am thinking of replacing handlebars with something more straight, with not as much pullback (would be better for my wrists). I realized that wiring is actually routed through the original handlebars, so it will need to be pulled out. What is the best way without damaging anything?
And I'm not sure if I will need shorter cables if changing to new handlebars. Any suggestions?

Thank you.

Cracked hose is the crankcase vent - it goes up to the air box. Not critical. Wouldn't hurt to replace it some time though.

Neither. Get the actual Honda service manual. Too many mistakes and omissions in both the Haynes and Clymer manuals.

throttle cable routing and lubrication are both critical. cannot comment re : modification.
to test a horn simply apply 12v+ and ground to the 2 terminals. if the horn works then i would proceed to clean the horn button contacts.

Thanks for the answers, I'll try your suggestions. Will have to order proper service manual and crank hose.

Gauges are mounted with rubber grommets. Perhaps you are missing them or have the wrong ones side to side?
Plus one on the Honda factory manual. Well worth the investment. ebay can be your friend for these, too.
The control connectors on the older Hondas are usually bullet plugs so they can be fished through the bars. You can either put the appropriate holes in your new bars, or just cable tie them to the outside. If you do that, you will need to cut a slot in the control pod so the wires have a place to come out. As I recall there is also an anti-rotation pin that goes into a hole in the bars. You can drill the hole or the pin is just a light press fit and can be pulled out. Lubing the throttle cables can make a big difference. As far as cable length, that will depend on your bars and how your controls are positioned.

Got to fix that rust issue.

If you don't it can cause major issues.

Start by changing the fuel filter and check it often.

I have a cleanable filter.

The tank issue is a major one to do it properly.

You have to basically remove the whole back part of the bike to get the tank out.

You could try it with it in place but results are mixed at best.

There are many ways to clean and preserve the tank.

Home remedies to commercial ones.

I went the Por-15 route.

re : rusty gas tank ...

i recently had a beat-up little suzuki 2 stroke with a gas tank that was pretty ugly inside. i had watched a few youtube videos on cleaning gas tanks using electrolysis and i had little to lose so i gave it a try ... i was gob-smacked at how well it worked ! you might want to look into it.

Honda service manual has been ordered.
Next, I'll research suggested methods for fuel tank cleaning and removal, this will be high on my priority list.
Maybe order new handlebars while I'm at it. Gauges will have to wait for now, they seem to be working, other than sitting a bit off.

I changed the handlebars on my 76 GL1000. As the bars were not as tall, I had to replace the clutch and throttle cables, also the upper reservoir brake hose.
Before pulling out the switch wires, tie a piece of strong string around them. This will make it easier to feed the switch wires back through the new bars.

I am thinking of getting these handlebars: https://fortnine.ca/en/emgo-7-8in-unive ... bar#76=631
Which clutch and throttle cables you used? Do you have part numbers? Also, which reservoir brake hose?
Thanks for the tip about wires, but I will probably just keep them outside of the new bars.

I sourced my cables from David Silvers and the brake hose from SIRIUSCONINC in the US.

Alright, thanks for the info. What was the length of the cables that worked for you, and did you have to specify it when ordering?
