Hi. I have just fitted a Mivv de cat exhust to my 2013 multi and correctly fitted the spring to the cable which operates the butterfly valve. When I switch the ignition on and the bike does its pre start checks the cable moves in and out once as it should but the engine fault warning comes on in the small round screen, and when I start the bike and rev it up the cable no longer moves as it used to when it was attached to the butterfly valve .The warning only says engine fault and does not specify whether or not it is to do with the exhaust Also when I was fitting the exhaust I tried to remove a sensor from the front down pipe(don't know what it does) so that the downpipe wasn't hanging on the cable. I just assumed that It would screw out but it didn't. It just rotated in its fitting. I don't know whether or not this could have dislodged something and caused the warning to appear. Any clues would be appreciated. Cheers Gary.
It sounds as if one of the oxygen sensors (known as a Lambda sensor) has become damaged and inoperative. It would need to be replaced and set up correctly. Part number for a 2013 Multi is 55212092A. Incidentally, you don't have to remove the front down pipe to fit or remove the cat or a decat pipe. Provided you remove the rear wheel, you can do it with the down pipe undisturbed - as I did yesterday, as it happens. @garyl
Hi Pete, Would the lambda sensor be the sensor on the front down pipe that I was trying to remove when I fitted the new exhaust. If it is does do you know how it is held in place as when I tried to remove it, it just turned round and didn't come out. Unfortunately I realised too late that if I had removed the back wheel it would have made the job much more simple. Cheers Gary
Here's a suggestion, @garyl. Take a look at the workshop manual for the MTS - here's a link: http://www.madcogz.com/MSTD1200s/wsm/en/home.html Go to Section 6 (Electric system), sub-section 8 (Introduction to the engine control system), last part (Oxygen sensors). There you will find clear photos of the Lambda sensors in situ, and photos of the connectors (so if you want to disconnect one, you can unplug it from the harness - no need to take to sensor out of the exhaust pipe). Lambda sensors typically have a 22mm hexagon which simply unscrews in the ordinary way. Except that they are often screwed in very tight, and seize or corrode in place. Added to that, you can't get an ordinary socket on the hexagon, you have to buy a special slotted one - search eBay for "Lambda sensor removal socket". It is all too easy to break and ruin the sensor and still not be able to remove the remains.
Hi Pete. Thanks for all the advice, especially the link to the manual.(excellent) I am just trying to get my son to save it for me somewhere so that I can refer to it later. I think that the Lambda sensor May be the problem as it was that that I tried unsuccessfully to remove. Cheers Gary.
