Heated grip - throttle sticking - lubrication?

[alex_rsa]

What is the correct lubrication to go between the throttle twist grip and the handle-bars because using my heated grips is causing the throttle to bind.

I have used 3-1 oil before and also grease (normal automotive stuff) but the throttle then ends up being very light for a while until the grease/oil eventually wears away and I am back to it binding.

Turn off the grips, sorted

I had the same problem. There is a fix, just search the forum for heated grip problems. All you need to fix it is a washer. Worked for me.

Some of the bikes use steel handlebars. As the throttle grip rotates back and forth over the bar, paint is worn away, causing the bar to rust. A layer of oxide slowly builds up between bar and twistgrip, causing the twistgrip to bind.

I would start by removing the right-hand switchgear and throttle twistgrip, and cleaning the inside of the twistgrip with methylated spirits and a clean cloth. Then take a look at the handlebar. If it's steel, and has rusted, remove all rust with fine sandpaper, then treat the metal with a phosphoric acid solution to remove what remains of the surface oxidation.
A lubricant? I'm not 100% certain... but colloidal graphite might work. Get it from any locksmith.
I've tried using teflon-based chain lube before. It didn't work - it made the grip action even stickier than the corrosion and dirt did! Same thing with red rubber grease. Oil and other petroleum-based lubes? No go - they ave potential to cause mischief in the vicinity of rubber parts - especially the grips, and the seals covering the switchgear micro-switches.

Aluminium bars don't suffer from this problem - at least, they won't unless they're exposed to salt. In any case, I'd be checking for dirt 'twixt bar and twistgrip.
Wash the bike frequently, rinsing with clean water and drying it off immediately. Good preventative maintenance.

Slacken off the bar end a tad to allow the grip to expand without causing friction. This sorted the problem on my 1150. As mentioned above, fitting a washer will provide a gap for expansion.

Normal grease will cause nylon stick. If the throttle grip tube is nylon (which is likely), light silicone oil should sort it.

Before you lube it up undo the bar end whilst the grips are hot. If it stops sticking space out the bar end with a washer and jobs a carrot.

Thanks guys, will try loosen the bar end first as that is the easiest.

The bars are not rusty as I had the twist-grip off when I replaced it last year so it probably is the bar end pinching the grip.

Washer is the way to go, it's a common problem and even my dealer suggested it. Loosening the bar end will result in the hand guard moving.

You don't even need a washer.

Solution 1:
Take bike off main stand and accidentally drop it on right hand side so handlebar hits ground.
Problem solved.
Solution 2:
Loosen the screws holding the right hand swith assembly to the handlebar.
Move it inwards 0.5mm & retighten screws
Problem solved.
First solution is the easiest one!
