Hi all - I have a 2014 CBR1000rr & just fitted (yet another) new cable to Akarop silencer (they corrode and don't last 2 mins)- the system has the exhaust flap and links to the servo same as the standard exhaust - does anyone know what positions the servo should be in on start up? Mine occasionally moves (you can hear it whirr) then other times doesn't move when I turn on the ignition - regardless it seems to be opening the valve as soon as the engine turns over so when it is ticking over the valve is fully open... I am also getting the yellow engine light suggesting something is amiss with the servo & exhaust flap system... also I can't rotate the servo by hand, it needs a tool... wondering if it is buggered... any advice appreciated
You should be able to turn the servo wheel by hand, to its original position which will remove the error code on the dash. If you can't it may be goosed
A lot of people (myself included) just remove the cable all together. The flap is sprung open in its normal state so you can just remove the cable from both ends and run with the flap permanently open. If you can't find the correct position of the servo motor to exstinguish the warning light or its broken you can buy a servo motor buddy which plugs in place of the motor and deals with the warning light. https://www.healtech-electronics.com/products/ese/
+1 on Charlie's advice. Don't be tempted to buy cheap £10 servo eliminators on the bay, Healtech is the way to go. It's plug and play just under the seat. A mate bought a couple of the cheap ones and one was given to me. What a waste of time. FI light came on when it wanted to. Health tech solved the problem straight away. Chin
I got a smartmoto one from eBay after recommendation from another forum member - ship from Greece but by UPS and arrived in days. Only £45 and very straight forward to fit. No issues and would recommend to others https://www.ebay.co.uk/itm/Stellmot...e=STRK:MEBIDX:IT&_trksid=p2060353.m2749.l2649
On RR8, the pulley rest position is around 12oclock when the engine is off. It opens the valve @ 40000rpm, may not be same as 2014.
I bit off piste, but the 2004/2005 servo looks like this with cables detached. With the cables attached, the 'full bore' position is such that the marker on the pulley and casing line up with each other. The 'at idle' position is such that the marker on the pulley points down at the little notch which you can see on the housing just below the face plate mounting tab (at about the 4 o'clock position). You can get a little plug which fits the diagnostic port and makes the servo swing round to the 'full bore' position so that you can tweak the cable alignment and get the markers to point at each other. The little plug just jumps two wires, so you could achieve the same result with a suitable bodge. If the cables have been removed, it seems to me almost impossible to reinstate them without taking half the bike apart. Here are the 2004/2005 cables and the diagnostic plug:
