ScottOiler

A ScottOiler is a vacuum powered automatic chain lubrication system that is said to increase chain/sprocket life by 2 to 5 times. We are here to see how easy they are to fit, if they are any good or not, and to test their claim of reduced chain stretching and wear.

We fitted one to a 1999 Kawasaki ZX9R C2 and here is the rundown on how we did it.

Inside the box were 26 parts. Fortunately I found that I only had to use about half of these.

Step 1	Remove what bodywork you need to in order to see the carbs. Also remove the seat so you can run a line from where you want to mount the bottle to the chain.
Step 2	Find a source of engine vacuum to run the ScottOiler. Four alternative connections are supplied for the engine vacuum. A 'Tee' connector that can simply be installed in any vacuum line, even in the vacuum line that goes to the fuel tap if your bike has a vacuum operated fuel tap. Or for carb' balancing holes M5 and M6 brass spigot's are provided. Where none of these options are viable, can't really imagine that, a universal spigot can be used by drilling a 5mm diameter clearance hole in the carb mount. Then inserting the provided M5 Spigot, nut and washers into the hold you just drilled. For rubber carb' mounts use drill a 3mm hole and use brass washers to seal.
Step 3	On the Kwaka' there is a vacuum outlet on the back of each carby' (normally used for carb' balancing), one of these was blocked off with a bolt. We removed said bolt and replaced it with a spigot that was supplied in the kit (see left). An appropriate sized washer for the spigot was not supplied in the kit, but luckily we had one just the right size on hand, we then installed this with a very light smear of silastic at the top of the threads.
Step 4	Find the position where you want to mount the SCOTTOILER bottle. Some people mount it on a frame down tube, some people behind the number plate, we chose to install it in the under seat storage of the ZX9R (see right), a minimum of 30 degrees from horizontal. The bottle has a clamp attached to it with a bolt and washer that can be positioned where you need it, then attached to a fixture. We drilled a small hole through the side of the plastic tool bag bin, and affixed the bottle here. It was now sitting where the bottle of Maxima Chain Wax normally resided, very fitting indeed.
Step 5	Connect the vacuum spigot to the bottle using the supplied thin, black vacuum line. At the vacuum nozzle (carb') slide the right-angled 'Vacuum Damper Assembly' over the spigot. Then slide the other end of the black vacuum (after it has been trimmed to length) line on to the top of the bottle.
Step 6	Now mount the 'Dispenser Assembly', which is basically the plastic nozzle at the end of the long clear plastic tubing. One end of the clear tubing fits onto the nozzle found at the base of the bottle while the outlet end is positioned close to the chain and sprocket. On the Kwaka' we ran the plastic tubing in the supplied 'dispenser mounting sleeve' which is a rubber pad with a hole for the plastic tubing to slide through. We glued these 'dispenser mounting sleeves' or how about we call them black bits or rubber from now on. We glued the black piece of rubber with the clear tubing running through it to the underside of the swingarm. (see right)
Step 7	The tubing was then routed up the side of the frame. (see left) We then routed the plastic tubing along the same route as the wiring to the brake light. With everything in place it was time to fill the bottle and prime the system. The bottle is filled with the supplied oil and then primed by attaching the supplied oil filling bottle to the installed oil reservoir, then squeezing it hard while the flow rate is set to prime. After a minute the clear line will be full with lube (see left) and you are ready to go. Set the flow rate dial to about half and then fine tune to your preferences from there. Aim for 1 DROP per minute to be released onto the chain at tick over. All in all it takes around 2 hours from start to finish.
