Hi
Odds are heavily that it's the new tyre/s.....I'm waiting to put a few more miles on them and will then change them both.
Others on the RAT forum have had the same, usually after a change of tyres.
I can confirm what it's NOT.
Not a) steering head or wheel bearings.Nor disc warp.
b) chain or sprockets
c) a fuelling map issue
d) almost certainly not a gearbox output bearing/ shaft problem.No sign of any wobble on the output shaft on external examination and perfect in all other gears and speeds other than 2nd between 25- 30 mph.
What I've also noticed v recently in addition to the pulsing is that at very low speeds( under 5 mph) I. Can feel a slight shimmy through the handlebars.
I'll post when I change my tyres and see what effect this has.
I took the Road Less Travelled.
Now where the ****** am I?

Have you string lined your front and rear tyres, to ascertain your centerlines reasonably match? Try that if your new tyres doesn't fix the issue.
