Hi Team. I have been bugged by the dreaded engine light which Dealer Tool diagnosed as exhaust motor cable malfunction. On inspection, the EV was only partially opening on the start up cycle. Using the "park tool" I disconnected the cables and found the EV very sticky. Stupidly I tried to cycle and test the servo without the motor attached and have completely lost the park mid- position. One cable is tight closed against the inner, fully retracted. I cannot seem to reset this electrically. The Dealer Tool open close cycle test does not work, so conceivably the servo is dicky. So how best to sort this? Can the servo be back wound or reset to allow reconnection of the cables? I assume the servo can be accessed without removal of anything else from the rear wheel arch. Or maybe junk the exup with a suitable eliminator module? If so does this screw up the fuel mapping? Must admit I didn't notice any appreciable noise or performance since the advent of the light which has been on and off for some time now. The valve is open. Any guidance would be much appreciated.
You can disable it with tunecu or with a servo buddy. I went with the servo buddy on mine as got scorpion exhaust and the link pipe removes the valve entirely so I removed the motor along with it. Presumably you can do this if its disabled with tunecu as well? If you can remove it, it's just a case of disconnecting the cables from the valve then I think the motor is held with 2 screws above the rear shock. I then routed my cables into the undertray under the riders seat and plugged servo buddy in there to keep everything neat and tidy. Sent from my SM-G991B using 675.cc mobile app
Thanks very much. I was tempted to try and return to stock but it may be more trouble than its worth. I suspect the servo is knackered and my be best eliminated.
So many known issues with them, eliminating them removes any chance of it failing. Sent from my SM-G991B using Tapatalk
I feel your pain mate, I had issues after fitting the arrow can. I couldn’t get it adjusted correctly even using Dealer Tool. I ended up taking it to triumph as their software was adapted further to aid with adjustment. I’d get a second hand servo motor, make sure the valve moves manually so is not sticking and get it to triumph perhaps? I paid 1 hour labour to have the arrow installed, software update and exup set up all together.
If you decide to go back to standard , I have a servo motor with cables, which are new old stock. From a 2011 track bike. Or some 2013 sets aswell. Sent from my SM-G960F using 675.cc mobile app
Thanks all. Finally I bought an EXUP eliminator module odd fleabay. Plug and play, so path of least resistance . It seems to work (started with no warning light) but not ridden it yet.
I just did this 2 days ago. First I cleaned and lubed the valve on the manifold but cel was still on, so I got the repair manual out and read through it. Took off the cables from both sides adjusted slack 15mm on servo side and 5mm on butterfly valve side. Lubed both sides with 3in1 oil. Started up the bike and after 3 run cycles the cel is finally gone, bike even sounds normal now. I decided to keep it as the bike is tuned for having it on and I have read how other stated it opens at intervals within the rpm range and to some does affect performance and sound. Hopefully this goes good for another 10 years like for some other members and I'll be happy. Sent from my SM-S908U1 using Tapatalk
Honestly no, nor any noise increase either. It may be a long time it worked properly that I’ve forgotten how it was standard. I’ve also reverted to standard gearing (inadvertently as I didn’t know the previous owner had lowered it when I ordered up the c&s kit) in this time so it was feeling less urgent or part throttle.
I didn't notice any drop in performance! Low down and if anything feels stronger in the upper midrange where the standard exup would still be partially closed, that may just be the increased noise playing tricks though. Speaking of noise, definite increase on my bike, on the throttle and on the overrun, mine has the Arrow with no baffle though.
