Chain Oiler Comparo, final update
Today I removed the Pro-Oiler from the VFR. Not because I don't like it. I do! But I am selling the bike, and the new owner doesn't want it. Better for it to stay here where it can eventually get used again, than to go in the trash when the new owner of my VFR comes to pick it up next weekend.
Meanwhile the TDM has been laid up all season waiting for brake work. First it was waiting for parts, and then the parts came in but by then it was full summer and I haven't wanted to take time away from riding the other bikes to work in a hot garage. While the TDM has been sitting there, the Scottoiler has leaked all of its oil out onto the garage floor. I have not worked on it, but my guess is that when I had to apply vacuum to prime it again, after I let it run dry last year, I drew in too much oil and I plugged the breather. As my garage heats and cools every day, it sucks up a little oil each night, and pushes it out onto the floor the next day. I'm sure it will be an easy fix, if I would just get around to it. But instead I intend to move the Pro Oiler to the TDM, since it is cleaner and easier to maintain and I now have one sitting on the bench just waiting to go on the bike. I'll be writing to the Pro-Oiler folks to see about getting the parts needed to fit it to the TDM.
The oilers worked very well to preserve the chains; they made chain drive almost as trouble free as a shaft drive. I intend to install oilers on all my future chain drive bikes. They are definitely worth having.
The winner of this comparo is the Pro-Oiler, but the Scottoiler is also a worthy competitor and you could do a lot worse than to use either one.
Since I started this comparo I have seen two other interesting oilers reviewed in magazines. Note I haven't tried either, or seen them in person. But this is what I think, based on the information available.
This oiler has an electric pump, like the Pro-Oiler (and the Hawke Oiler). It is not as complex. It is programmed by choose a flow rate that will apply anytime the unit is powered up. You just attach it to switched power; no need to wire it into the speedometer circuit. So it's easier to install, but not as fine-tuneable. It also has an unique and ingenious oil reservoir; the oil is stored in a wide piece of tubing that you can attach to a frame spar or other out of the way spot. Which I think is clever. But the applicator is a single nozzle, and the tubing that leads down to the chain is a larger diameter than I think is optimum. I therefor predict that the Cameleon oiler will leak more than average, because you'll have to feed more oil to get it distributed, and because oilers that use that wider tubing leak more while parked. Not a big deal, just something to be aware of.
Scottoiler eSystem (see image at top of entry)
This oiler has an electric pump, like the Pro-Oiler, Hawke Oiler, and Cameleon. But it has a novel control mechanism. It uses a triple-axis accelerometer to determine when the bike is moving, and it uses this info to meter the oil. If it all works as promised, it should be easier to install and still offer very precise metering of the oil. I know that Scottoiler uses the small tubing that I have decided is preferred, so it seems like there is nothing in this package to dislike. It also displays the ambient temperature, which is like getting two farkles in one. The Scottoiler eSystem intrigues me, and if I were buying another oiler today I might go for it, in spite of it being the most expensive oiler on the market.
