Probably no way to do it without taking the nose fairing off. Which pretty much means taking all the fairing off..
It's not actually too difficult, and there's a reasonably comprehensive pictorial somewhere on the site. Just follow along, be careful.. And take note of where the various bolts/screws/fasteners install.
When I first dismantled mine, I noted original placements using my camera, and stored each set of fasteners in labelled plastic baggies.
The nose fairing lifts off without too much drama, but it is a tight fit, especially when you put the thing back on.
woof is doubtless correct, and your stuck mechanism is likely due to one or more of those pesky rubber gaskets getting jammed in the works. Once you have the fairing off, you'll be able to assess the situation, and extract the rubber bits. Throw 'em away, if you like, or replace them with some pieces of bicycle inner tube. Glue 'em in place with some black RTV silicone.
Also, once you gain access, check the cable tension on the rube-goldbergian mechanism. It may require re-tensioning. Note that the tensioner has a locknut, and is a flimsy POS. Take care to not overtighten. All the cable guide wheels should turn smoothly, and there shouldn't be any noticeable slack in the cable.
Take your time with the job.
Good luck
