1 ABS brain teaser Thu May 19, 2011 8:46 pm

Some of you may have been following the thread 'Are radials worth the effort?'.
I am looking at the feasibility of fitting the rear wheel and front end from a K1100RS to my '89 K100LT in order to fit radial tyres for handling and the improved four pot brakes.
I have all of the parts now but one problem has arisen and this is were I'm looking for feedback to an idea I have had. The problem is that I may have to remove the ABS to make the changes as the 16v engines used a slightly different system.
The rear wheel is no problem as the same components for braking are used. So its almost a straight bolt in.
One of the components of the 8v ABS system on the front wheel is the sensor ring. This consists of a metal ring with a series of sections cut around the edge and is mounted behind the right disc.There is a magnetic pick up fixed close to the ring which tells when the wheel is about to lock and releases the pressure before it does so.
The 16v uses a similar idea but the sensor ring is mounted 'flat', on the same plane as the disc.
At first I thought they would be incompatible and the ABS would have to come off.
But after a bit of thought I measured both sensor rings and found that both have exactly 100 notches and the 8v is 19cm and the 16v is 18cm in diameter.
My idea is this. If I changed the front end over and plugged the 16v sensor into where the 8v sensor was plugged in, would the ABS still work?
The only other change to the braking system would be using the 16v master cylinder with the larger piston and I don't think that would effect the ABS system.
I can't see why this wouldn't work but would like to hear other opinions.
