I just finished installing a Scottoiler on the Blackstrom. I'll add some photos to this post once I'm not so tired, but basically, here's how it went:

The first thing I had to do was find a place to put the reservoir. Finally I noticed that there was a plastic trim poprivet (the kind you push the center in to remove, then pop the center back out to re-insert, that holds two plastic trim pieces together) right beneath the rear left fender where an exhaust pipe might be if the Blackstrom had dual exhausts. I popped it out and looked at the mounting bracket for the reservoir and yep, the reservoir's mounting stud was almost exactly the same size as that hole. A couple of washers later, and the reservoir was mounted. Most people mount it inside the rear left fender rather than hanging under it, but I like it outside so I can glance at it to see if it needs filling and fill it up without taking the seat off. Besides, to put it inside the rear left fender I would have needed to take the plastics off, and that would have required taking the rear luggage rack off, which is a PITA...

The next thing was to route the vacuum line. The Scottoiler uses engine vacuum to open a plunger to let oil drip out onto the chain. That keeps all your chain oil from dripping out when the bike is off. I had to glue one guide onto the plastics in order to keep the vacuum line from flopping into the wheelwell. Oh well. It's hidden up under the fender, and from there the vacuum line goes through an already-existing hole in the plastics and forward to the forward throttle body, where it plugs into the throttle body sync port (previously covered with a vacuum cap) using the adapter in the kit. At some point in time I need to re-plumb this port with a "T" so you don't have to pull off the Scottoiler vacuum hose to sync the throttle bodies, but this is okay for now.

The last and final thing to do was to route the oil line. I routed it basically down the rear subframe member until reaching a point where I could hop it down to the swingarm, then of course to the side of the swingarm, then down underneath it until I could bend the nozzle so that the tip was just above the chain at the sprocket.

Once all that was done, I could prime it. I use GM Dexron III ATF as my chain lube in my Scottoiler on my KLR, so in the interests of keeping a common lube, I primed this Scottoiler with ATF also. Unlike the weird "Scott-oil", Dexron III is available for cheap at every Wally World and roadside Kwicky-mart in the USA, so it makes more sense to put ATF in the chain oiler if you intend to take long trips, as I do. So I shoved fluid into it using the sealed priming intake port until nice pink fluid started dripping onto the chain, then popped the cap and finished filling up the reservoir with ATF.

Tomorrow I'll need to calibrate the thing to have the correct number of drops per minute. It doesn't take much, I don't intend to ride this bike through the dirt so I just need enough slow drip drip drip to keep the chain o-rings moist and conditioned and keep the chain from rusting. Any more than that and it just makes a friggin' mess. But in case it's raining or I do go through the dirt or something, all I have to do is turn the dial turn make it drip faster, and there we go. A mess on the back of my bike is better than having a rusty chain, after all...
