My abs light is now on full time, and Steptoe has pointed me in the direction of this Youtube vid, which shows how to rebuild the abs module.

Before I go and end up with my bike in bits on the garage floor, has anyone tried this?
Yes I have. Couple of dodges worth considering.
1, When taking the motor off get a junior hacksaw blade and remove the pins on one end so you are left with a pull action blade with no projections and use this to carefully cut the peened indentation of the locating lugs off. This gives a really neat finish. There are some vids on youtube showing the use of milling cutters and all sorts to do it and it's not necessary.
2, Be very carefull when displacing the locating blades inside the motor to get the cover off after drilling access holes in the body. I used the semi circle of stiff wire method but still managed to break one off and maim the other, and I'm a reasonably skilled engineer, so you've been warned.
3, If you intend to make a bracket to hold the motor in place similar to Andy's, as i did, and drill and tap the lugs for retaining bolts, the little triangular one is positioned right over the end of the drillings that locate the mounting frame bolts. This means the new tapped holes will be short and will just interfere with the mounting frame bolts. The answer is to pop a washer under these to give your new bolts some clearance. The aluminium of the valve body is very soft so don't go tightening them up with a windy gun either or you'll strip your carefully tapped holes out and many bad words will ensue!
