CX500 GL500 650 Global

This morning I was getting ready for work, in a hurry as usual, before dawn. I dragged my GL500 Silverwing out and pulled out the choke full, then started the bike. It cranked immediately, then stumbled a few times and quit. It restarted immediately and then quit again. Of course I'm standing out in the driveway in the dark so I couldn't see immediately what was happening. It appears the choke was slipping right back in as soon as I released the knob.

I've never had the choke slip before. I'm going to have the same problem tomorrow morning if I don't find an easy fix for it between now and then. Unfortunately, my work shift is 12 hours so I won't have a lot of time to play around with it tonight after work.

Does anybody have an ideas why it's slipping? More to the point, does anybody have any idea how to make it stop?

Hi. The black round knob below the choke button is a friction nut. If you turn it clockwise, it tightens the friction to hold the button in. Sounds like you accidentally turned it anti-clockwise a bit and it's now loose - or it may have worn a little over time and slips.

They've done it to me before.The Nylon Screw/nut can work it's way lose as well.I put a bit of RTV(Silicone Gasket) on the threads on one of mine just to stiffen it up.
