Put on new tyres...
Brake binding on LH caliper and ABS acting funny.

Bottom line .....new discs n pads.
Test drive to bed in, seemed good but then after braking
to slow down then braked and no front brake then suddenly
locked on. Repeated this.

Checked sensor - the space was excessive.
I took off 2 shims but haven't tested it yet.

What is affect of too big a gap at sensor?

Thanks in advance

Well, too large(wide) of a gap can cause the ABS to not "calibrate" when rolling out and giving you alternating flashing fault lights.

Not to assume, what is your brake fluid level in the sight glass of the MC. Is it above the window?
When was the last time you did a full brake fluid flush.

When you re-installed the wheel axle shaft thru the forks, did you tighten the end bolt 1st, then thump the bottoms of the forks(I use a rubber mallet) to let them self 'align' before you tightened the 2 fork bolts? (it help the upper/lower parts of the fork to align to each other to reduce friction wear of the internal brass bushings) DAMHIK....

If your front brake is locking then it may be that a line has broken down internally and is clogging things. A failed or too much gap ABS sensor won't cause that to happen.

It may be time for a refit to new or stainless braided brake lines.

It braked OK but didn't try abs function.
Not sure I want to do that on the road.

I did braided lines a while ago.
Fluid is good.

Testing the front ABS is mentally intimidating but it's not very dangerous as the whole point of ABS is to keep the tire from washing out.

Just get the bike going maybe 25 MPH going straight on flat level surface and slam on the front brake. (For obvious reasons do not do this with a vehicle behind you.)

I've had the front ABS engage several times on my Ks in real life riding and it is not a traumatic experience.

Don't try this if your ABS warning light is flashing because that means your ABS brain is in fault mode and the ABS is not working.
