Like all long term Triumph users, I hate the EXUP valve. I had my 2014 Daytona 675R working for a while, I think a year or so since my last adjustment, but it's decided to start screwing with me again. I've always used TuneECU with the bluetooth connection for error codes and adjustments. It's able to run a "test" of the EXUP valve that just moves the valve and sometimes spits out an error code, but no details about adjustment as described by the manual (too loose, too tight, etc.). It also can put it in the adjustment mode, where one should be able to set it to a centered place to adjust the position of the closing cable. In the past, I've been able to clear my P1080 code this way.
Right now, I'm having trouble. Often, the valve won't move at all during the test mode, even if I've cleared the code. I suspect this suggests that it knows it's off in some way and would normally transmit a more detailed description to the dealer's software. I can still usually go into adjustment mode, where it'll make a buzzing sound as if the motor is struggling to get to the correct position.
I noticed the opening cable might be a little tight, so I loosened it. When it's actually kind of working, it'll open the valve and turn a few times in an attempt to take up slack from the open cable, but doesn't quite do it. However, when I tighten the opening cable, it has even more trouble opening up.
Sometimes, after cycling the bike on and off, I can get the adjustment to reset to normal.
I've taken the cables off and the valve moves freely, hot or cold. The cables slide freely as well. I've even taken apart the servo mechanism. There's a bit of electrical motor smell (same smell you get from a heavily used drill) but everything else looks appropriate and moves freely. Maybe there's something wrong with the motor, hard to say. There's a rumor out there that opening this thing up might mess things up because you'd be changing the number of turns on the screws, but that's not how it works. There's a position sensor that attaches to the large screw that operates the pulley cam, so whereever that cam is should be what makes the difference.
Wondering if the DealerTool offers any more function than TuneECU. I'd like to see if it will give me anything about particular cables being tight or loose, etc. Otherwise, I'm buying a new servo plus cables from eBay. Hopefully replacing that part will fix the problem.
And yeah, I know I could just get a servobuddy and a PC, but that's kinda pricey.
