It's sorted.
I returned the
dampening and preload to stock settings and the odd rumble has gone. Looks like I had the perfect feck-up settings combo between the two of them.
Throttle cable also sorted. Stuck on a bash plate from a company around Bob's place (like 50 metre down the road from his house).
It's now perfect. I just love this bike.
Cheers again for advice.
Now I'll sit in and think about not wasting the money riding it anywhere!
