Lansdowne dampers not damping...

This has already been mentioned on the list but changing the fork oil is very important when you have the spring inside v. outside.
Even with low annual mileage you can get water along with metallic sediment build up. At least with Commando forks you can change out
the bushes but despite the bother removing and completely cleaning the sliders is a good idea.

Tis a fair point. Well put.
 
Tire/fender clearance issues - I'd also check for fork twist, wheel bearings, and wind deflection, as well as tire growth at speed
 
The wheel and tyre spin beautifully when on the centre stand. Rubbing can only be due to tyre growth at speed I suspect. Lesson learnt: allow more space for tyre growth!

I don’t know why the fork oil lost viscosity, I do confess I did not change it annually, but my mileage is pathetically low, so this really shouldn’t be a reason. Fork oil is one of those things I don’t tend to put much thought into, I tend to buy whatever is on the shelf when I need it. Perhaps I used cheapo no brand stuff that just wasn’t very good? Second lesson learnt: use good brand fork oil and keep a note of what, and when, its used!

On the bright side, the rubbing must have been causing quite some drag. So sorting this out should yield a small performance boost...

And the carbon mudguard will reduce unsprung weight too...

So at least I’ve kept to my personal philosophy of always putting it back together (slightly) better than it was before!
On my commando I could hear a droning noise Evey time I went above 90 mph
All became clear when I noticed my fresh paint bubbling off my front mudguard
I don't know exactly how much the tyre grows at speed but I'm guessing 10mm or so
 
WM4 that is good. Running Avon AM26's ? it is tight even with the stock 850 SS fender and stays.
I thought of splitting my GF Production racer fender down the middle and adding 3/8th inch material to the fender.
Food for thought?
maybe?
cheers,
Tom
