I've never owned an ABSI but the key would be the mounting positions.
According to RonAyers.com the fork lowers (where the calipers mount) are different part numbers.
It is hard to tell if the mounting positions are different or not.
You probably would have to have them side by side to figure it out.
This is what I used to connect the two 'ports' from each caliper -

Thanks UP,
I'll see if I can get a look at an ABS1 model and take a few measurements. Thanks for the link.
 
So I got the caliper off tonight and yes, one of the pistons was seized. I have a pair of those pliers that expand and grab the ID of the piston. Nothing. Didn't budge. Time to get the "I'm not asking anymore tool".....I modified a banjo bolt with a grease fitting and a sleeve to block off the open ports. Screw it in and connect a grease gun. Popped it out and cleaned out all the grease. Still doing the cleaning but I don't see any major damage. Some minor pitting in a unused portion of the piston, should be good.
This would also explain the uneven wear on the pads. Braking should be greatly improved after this. And yes, I'll be doing the other side as well.

Hi Uncle Phil,
Always respect for your knowledge and posts that I have followed for years.
Do you know are the 3 pot front calipers from the early ABS a direct swap out on the mounts on the forks for the non ABS 2 pot calipers, or would it need a fork change as well? I like your idea of plumbing in the centre piston to give more braking.
Regards,
Gc

The early ABS use 2 pot calipers as it did not have linked brakes.
