Yes it does look slightly fiddly,I really like the idea of the Cobrra system and it looks really tidy,but could cause your bars to be cluttered if you have phones,heated grips controls and satnav units mounted aswell.I had a tutoro on my 990, it was ok, a bit of a pain to set up though.
My personal opinion is that once set up correctly an oiler is almost fit and forget,and seems to keep the chain relatively clean.Why do you need an oiler on a sealed O-ring chain? Surface rust?
I had fitted it in the inside using SW-Motech's clamp and custom made metal blade. For what I have seen, the outer vertical edge of the chain cover can touch it in the unlike (for me) event of bottoming the rear. But, it is easily resolved by cutting out that area of the chain cover.Nice little family run business as well - just across the Severn Bridge from me. Good people to deal with and I have just fitted one to my ATAS.
I fitted it on the LH pillion hanger, but on the outside of it. I have to say it is a little exposed to the adjuster being knocked, but I couldn't see any realistic alternative position. Will have to see how it goes.
Having said that, oilers use very light oil, which IMO is much easier to clean off then the goo that it lefty spray cans.
Any interference with the center stand usage? I find not easy to use the center stand with the side panniers because of the tight space there, if you add the oiler reservoir isn't it even more difficult?Here are pics of how my oiler is mounted on my ATAS. I have about 2000 miles on it and I am happy with it so far.
