so had a chance to try the bike with one caliper tied up out of the way and went for a little run and then tied the other side up out the way and went fro another little run.
Results are a little odd.. No pulse through the lever on either run but definitely a bit of rumbling from the front end enough to still shake the mirrors a bit. Wondering if this points more to front wheel bearings. I'm guessing that with both calipers on it's trying to pull the wheel either way causing the pulse through the lever as the brakes favour one side then the other. And with just one caliper on it isn't constantly trying to fight that force... It makes sense in my head anyway.
Now, I do remember when I had the wheels powder coated that the front bearings were, what I considered to be very tight going in. Because of this when it came to fitting the rear wheel I sanded out the bearing seat to remove any primer from the powder coating process. So, it could be that the front bearings have been too tight... There doesn't appear to be any play in them on rotation while up on the jack or side to side (checked by holding top and bottom of wheel and then rotating wheel 90 degrees and pushing again etc all the way around). Head stock bearing also appears fine, no notches and doesn't settle in any position when front wheel is off the ground.
Have ordered new bearings for the princely sum of £8 so worth a try. Will remove old bearings and clean out bearing seats to make sure they are to bare metal.

It wouldn't be fun if it was easy, I just wish it wasn't this much fun.
