K1200RS ABS Delete

I have purchased a 2003 K1200RS that the po has bypassed the ABS. All the excess lines have been removed and the u bends installed to reattach the front and rear brakes. I have no brake light, cruise control or speedometer. The bike still has the pump hooked up. I have removed the pump body, separated it from the ABS ecu, re-connected the ecu, checked both brake signals and power (both keyed and constant) at the bulk connector. I noticed it has a badly burned spot on the circuit board when I removed the ABS ecu. I suspect this is why I am not getting anything to work. My question being, is there any way to bypass the ABS ecu and get the speedo to work. I have googled my self blind and all I have worked out is the work around for the brake light. I did a bit of looking for an ABS ecu on a bad servo but have had no luck. As I understand it I should have everything functioning with the ABS ecu still connected and powered up. Does anyone have any suggestions? Thx in advance

ID:	21873I have read in one of the forums of a member re-soldering the lands on a damaged PCB, is the damage such that you could repair it? Alternatively buy damaged ABS unit and use the circuit board from that.
Found the photos, it was on the I BMW forum.

ECU Board

I would love to find a good ABS ecu portion. Not sure if that will happen very easily. My board is burned pretty bad. We have an electronics department at my work that is going to give it a look later this week. Where is the I BMW forum? Thx Stacy

On the servo-ABS units, it's the electric motors that usually fail, not the board. so finding one with intact circuit board should not be too hard. I'd try Beemerboneyard.com Give them a call and tell them you are looking for a non-working servo-abs unit with the electrics intact for parts. There are plenty of failed units out there, just have to find one for your bike. They pop up from time to time on Ebay, as well. A bit of a gamble, I'll admit, since there is no way to know what part of the unit has failed, but you have to start somewhere. Since you need a "non-working" unit for parts, should be real cheap. Another source might be Module Masters in Moscow, Idaho. They have been trying to come up with a rebuild for these servo units for years. If nothing else, they should be familiar with what you are looking for.

I have had good success with parts from Motorworks UK - https://www.motorworks.co.uk/vlive/Home/index.php

I totally removed my ABS a couple years ago now and reckon the bike is better IMO.

Do a search under: "K1200 ABS-ectomy" or K1200 ABS removal. Lots of info on line how to do it.

I've just completed an ABS-Ectomy last weekend. It's not for the faint hearted and takes about 6 hours.

I bought the kit from Motorworks, removed the ABS unit, the old brake lines, took the warning bulb out of the dash and removed the ABS relay.

On the GT it's a fairing and tank off job. I removed the ABS control board off the ABS unit, fastened a box and recounted on the bike, this gives you your brake light and Speedo back.

For the UK guys. Insurance. Yes I've told mine and good job too as they refused to continue cover.

MOT. I've had a word with a mate who is an MOT Centre and yes it will fail if there are any red warning lights on, flashing or otherwise. The rule is "if it's fitted it MUST work".

I've done a test ride and it rides and stops great.

Regards and Ride Safe
