Throttle Sticks

Postby rowejimf » Mon Jan 30, 2012 9:10 pm



Hello,

I purchased a 1977 Honda GL1000 from A reputable fabricator in Michigan. It was converted into a Cafe Racer and actually looks pretty cool.
I'm having some issues with the throttle as it sticks open as I let off. Is there a way to adjust it that you are aware of? The start button is also sticking when I go to start the bike. I really like the bike and want to make it the best that I can.

Thank you,

Jim

The throttle on the carbs should have a pretty good spring to snap it closed.It's attached at the cable end,on the carb.There is a 6mm bolt that can be loosened and let the spring to unhook from the plate.
It may just need to be re-set and secured.
As far as the start button,split the case,carefully disassemble,clean and lube.

There is suppose to be 2 cables on the throttle.One to open,one to close

It could also be old, sticky cables. If there is "stiction" in the cables (resistance to initial movement), you could try lubricating or replacing the throttle cables.

I have seen sensitivity in the grip response as well. You need to be sure the grip does not drag on the brake lever. I should work very well when you work out the culprit.

Both cables are intact, it doesn't appear to be as smooth as you'd expect from a normal operating
throttle. I have a 2010 Interstate that operates silky smooth, so I will try to look at everything recommended, grip,
lube, and possible adjustments. The grips aren't stock grips and the bars are set up as a cafe racer style type.
I'll find out what the culprit is.

Thanks,

Jim

My bet is that the PO failed to shorten the stock cables when he dropped the bars to cafe style. This is somewhat common when folks change the handlebar. Long cables do not route as well.

Fred, you may have hit the nail right on the head. I'm going to take a good look at it and see what the deal is. At times it continues to rev even after rolling off the throttle. I don't want to be pulling any unintentional wheelies :o I'll let you know what I find out...

When I got my 76 the throttle did not return at all. I replaced the cables and still had the problem. Turned out to be not enough tension on the return spring at the back of the carbs. Loosened the 10mm nut used a srewdriver to tension the spring and retighted the nut. Has worked perfectly since!

Have you got the throttle sorted out now?
Mine had the same problem and ended up being where the inside of the throttle grip was dragging on the end of the handlebar. Moved the throttle/killswitch housing slightly towards the end of the handlebar and that cured it.

One other thing to look at. I replaced my foamies on the grips and when putting the right grip back on I pushed it too far. It caused the throttle to be stiff and not snap back. It was rubbing against the switch assembly. Once I backed it off all was fine. Just a thought since it's got different bars from stock.

Great tips guys. The cables it turns out are a-ok. The carbs are in need of some adjusting. Randakks described it in one of his articles as a "Lazy / Slow Return to Idle (or Erratically High Idle)". There are so many possible things which could cause this condition, so it may take some time to get it all sorted properly.

Thanks again.

The slides in the carbs are vacuum operated, not pulled by direct cable like most bike and snowmobile carbs, If the slides are oxidized they can hang up. You can pull the top covers off and remove the slides and do some little polishing on the center post and outside of slide if corroded, Just don't remove any actual material,as it can affect the vacuum draw. Randakk covers this also in his tips.

Thanks Keddano.

I picked up an inspection mirror today and will have a look at the slides. The carbs have been cleaned, plugs and oil changed (black as tar), flushed coolant, changed the final drive oil, adjusted the valve clearance and a host of other things unrelated to idle issue so have made good progress in insuring proper functioning. I'll post more as I learn more. I've learned tons from you all thus far.

Thanks a million!

I doubt that that cable from the 1200 is going to operate correctly on your 1000, you should really use the correct one to ensure proper operation and your own safety. Having said that, there are two adjustment built into the pull cable; one at the handlebar and one inside the shelter along side your air cleaner. You can try adjusting the one at the handlebar first and spray some WD-40 on the return spring and also look for binding. If that fails you can then try the other adjuster under the shelter. A new pull cable for your bike is around $13 - $27 on eBay.. I purchased one recently and just installed it today.
