The ABS1 (1995 and older ST1100) modulators which come for repair are increasingly showing that someone has mis-adjusted the limit switch in order to avoid having a trouble code set. This,of course hides that the modulator is not operating.
If buying an ST1100 with ABS/TCS it may be advisable to consider this potential since the ABS will not function and a new modulator costs around US$3,000.00.
The up side is that they can almost always be repaired.
If someone would like more information as to how to perform a check for this, let me know.
The limit switch is under the white plastic cap on the top of the modulator however adjusting is not a simple task. I strongly recommend forcing the rear ABS to operate before purchase. The reasons I advocate forcing the rear to deploy are, IMO:
1) Locking the rear tire is less likely to be hazardous than is locking the front.
2) The rear ABS will not operate unless the front has passed the self test.
This will not eliminate a mis-adjusted front limit switch but will cover most other conditions which might have been hidden.
The way to absolutely conclude that the front is working, for the average rider, is to force it into ABS.
