Had a senior moment today.
I have not used my SR much over the past couple of years partly due to other bike projects and partly due to the alarming shuddering from the Triumph TLS front brake. I finally got round to investigating it today - I had convinced myself that the drum needed skimming so I have booked the wheel in for tomorrow to have it done.
So it was up on the bench, ratchet strap the back end down to lift the front wheel up and out with the wheel.
While the front was in the air I thought I would check the steering head bearings and discovered a helluva lot of play. I remembered that I replaced the fork stanchions about four years ago and it looks like the head bearings have settled in and all the grease had squeezed out and made them really loose - doooooh

The drum does not look in the best of shape so I will get it done tomorrow anyway but if it was just a little out then that would be magnified by the sloppy steering head bearings.
Looking forward to riding it a bit more now after replacing a set of moody mag pick ups and brushes and sorting out a sticky clutch so it goes well - now I should be able to stop as well!
