It's a '96 Evo Fatboy. My bad, I posted a question in the EVO section and then by mistake the follow-up here.

 

Clean the speed sensor in the trans..

 

Dude, thanks. Problem solved, the first time this century cleaned and it showed - unless HD did it at the first service I think that was the first time ever cleaned! Getting a minor tremor now so will give it a week then maybe clean again, had no idea how much **** that thing collected.
