Oh hell!!Many thanks to everyone who has made suggestions.
I was going to bite the bullet and order some Amazon Prime budget special bar end mirrors... but
Two things have happened
1) I discovered I don't actually need mirrors to be legal in the UK (I need them, obviously, to stay safe but hey what the hell!)
2) You know those 8mm chain adjuster bolts in the alloy swing arm? Both of mine were seized solid. I say both but in truth now there are only one and a half seized solid....
So priorities have changed....
Thanks for that reminder
When i get home I’m gonna squirt some WD40 on my adjusters
