RE: RS ABS Problem
(1) Is your battery getting tired - low voltage when starting the bike can result in ABS faults.
The battery definately needs to be replaced. A month away from the bike last August and the alarm flashing light drained the battery to 'dead'. So that's one thing to do.
(2) Check the brake fluid level in both the front and rear reservoirs- if either has run dry you could need a system flush & fill (note - as the brake pads wear, the fluid level will go down - doesn't mean you have a leak, just worn pads)
The bike has just been serviced (at a cost of €650!). The mechanic knows what he is doing (I believe) as he was the head mechanic at a BMW dealer until recently. New pads were fitted front and rear so I have to pesume that fluid levels were checked.
(3) Check the abs sensor gap (you should have a feeler gauge in your tool kit and the owner's manual gived the procedure and spec.
If the gap is wrong (and I personally believe this could well be the cause because of the hissing sound from the front as the brakes are applied), how is the gap changed?
(4) Last (but not least) - when was the last time the system was flushed? - the rubber brake hoses on earlier K bikes can react w/ the brake fluid and turn in into a gummy mess that will cause pistons in the ABS modulator to stick - the cure could be to give your dealer a few $100 to flush the system if you're not up to doing it yourself.
I would guess never. So I now know that there are at least 3 different things that could cause the problem in my case. Reading the cost of an ABS replacement controller unit in earlier posts, I hope it's one of the above.
