Well, after a day of checking....including wheel alignment, I concluded it is indeed a drive chain issue.
A call to Jack Lilley was cheering....'If you get it here( here, being 50 miles away) in the next hour we'll look at it BUT our currency is chocolate....bring a bar with you.'
I did and we jointly concluded I have a stiff chain link.
OK I can live with that assuming it'll last for my trip to Scotland next week.
Have to say I continue to be mightily impressed with Lilley's.
Helpful, knowledgeable and human.
These are the guys who wrote( without charge) the report on my Thunderbird LT which persuaded the factory that it needed a rebuild....and back then I wasn't even a customer of theirs.


I took the Road Less Travelled. Now where the ****** am I?
