Looking at it that groove/ recess in the middle must sit in the frame somewhere ? Either a hole or a u shaped cut that is a similar width ( obviously ) to the recess in the grommet. Can only be wiring loom ? Brake line ? Fuel line or cables surely ?
It's getting on my chuff now and it isn't even my bike !
I'll strip my GS down until I find it..
Steptoe will know but he's been stuffing cake all day so is beached .,
Is it a lost part that got dislodged somehow?
Noticed the cover on the front wishbone bearing was missing on my bike...it defiantly had one when I bought it. Fitted a new one then when I removed the tank a while ago to do the fuel filter there it was, wedged in behind the wiring loom. Just a thought
