Hmm. Forks put back in and I have a slight clunk on 'lunging' them up and down. Pretty sure it's not the head bearings (new top one also fitted) as I can't feel any fore and aft movement. Thought it might be slight play in the semi-floating disc mountings but perhaps not. I might nip the head bearings up a tiny bit tighter and try again just in case it is that but it sounds like its coming from the forks.
I need to get the lad to help me by getting them moving with the front wheel up against a wall (so eliminating brake caliper/disc effects) while I crouch down and listen carefully. Otherwise, I can see me having to drop them out again and check them as best I can off the bike. It seems to be right at the end of the travel though, so tricky.
Didn't seem to be a problem with the bushes on inspection by Revs and no suggestion of play in them once assembled as far as I could tell. I've tried loosening the spindle clamps off and lunging on them to make sure everything is lined up OK.
To be honest, it doesn't bother me that much but the MoT tester may not be impressed.
