Evening All, does anybody know how to fix a throttle that sticks when twisted and does not spring back. Not in the habit of having the S@#! scared out of me lol. Thanks. Andy.

Replace it, the spring is probably weak, broken or dislodged could also be down to moisture/ rust.

I would simply spray it well with WD-40, as this can free stuff up and it also prevents corrosion. Electrically its also good. Work the grip back and forth, clean off the excess once it works again.
WD-40 is safe on plastics and electronics....and is available almost everywhere, plus its not expensive....one can usually does years of work!
Once a year do the same BEFORE it starts!
In the RN years ago, the fuselage of our Helis was magnesium. Magnesium gets "eaten" by salt, and we were flying over salt water, we washed the whole fuselage down with WD-40 after each flight, I never saw the slightest sign of corrosion!
A light spray and wipe over will clean a bike frame and prevent/slow down corrosion at the same time!!
Wonderful stuff!

As it's Old Farts day, we used to spray WD40 into the engines of Nimrods after they had flown over the sea. I use TT Spray from Tetrosyl, which has a wax in it, that keeps the rust at bay, like Waxoyl. Asda maintenance spray is similar, if still available. Riding on salty roads on aluminium-framed bikes needs some maintenance.

All throttles do this, even from new in my experience

Strip down and apply silicon grease to moving parts should free it up. It’s an annual task.

Throttles only really need replacing when the hall sensor fails. Always have a spare, pre-lubed throttle on hand for such an eventuality. 108x throttles are the best I think.

So would you say WD 40 is ok for the throttle?

Not sure if wd40 would be compatible with the rubber seal

It’s plastic-plastic, low relative velocity we’re dealing with, so some type of grease is called for, but probably not a petrochemical based one.
