Fitting a Scottoiler to an Africa Twin

Fitting a Scottoiler to a Honda XRV750 Africa Twin.
I've detailed below the process that I followed when fitting the Scottoiler Mk 7. The whole process start to finish took me approx 5 hours.

Before you start ensure that you have the Scottoiler installation manual to hand.

1. Remove the seat and the left hand Side Panel on the bike. That's all that needs to be removed.

2. The first step is to fit the RMV unit (item 1). I recommended that it is fitted near to the rectifier on the frame. You could just strap it to the frame but I suggest a solid fixing by using the Bolt On Clamp Set (BOCS) (item 11). Click here to see a picture of how I mounted it. As you may see there is a spare bolt hole on the frame member below the rectifier, this is not the one that the Side panel screws in to, it should be above this.
I took apart the BOCS and using the L shaped bracket I removed the bolt thread and drilled a hole in its place to take a bolt suitable for the hole in the frame member. An M6 possibly??
I reassembled the BOCS putting all of the nylon bushes ahead of the L shaped bracket at the end and bolted the bracket to the frame member and tightened the BOCS up. This provided an excellent solid fixing.

3. Next step is to connect the vacuum tubing. This was potentially the most troublesome as I had no idea where to start. However it turned out to be the easiest! There are several methods available for picking up the vacuum connection. There is a balancer pipe between the two carbs that you could cut into and using the Tee connector (item 7) get your connection that way. I wasn't happy to do that though. If you use the M5 brass screw-in Spigot (item 5) it is much easier and looks more professional. Click here to see a picture of the spigot in place and with the vacuum damper assembly (item 4) in place as well.

The first step is to unscrew the bolt already in there. This needed a hex key on mine.
In its place screw the M5 brass screw-in Spigot (item 5).
Fit the vacuum damper assembly (item 4) on top of the M5 brass screw-in Spigot (item 5).
You then need to run the thin black vacuum tubing (item 3) from the vacuum damper assembly (item 4) to the top of the RMV.

4. Next is the Dispenser Assembly (item 18) and possibly the most fiddly. There are two problems here, how to attach the dispenser assembly to the swinging arm such that it looks good but doesn't come off, and also how to overcome the problem of the derailment plate fitted to the sprocket. I took Scottoilers advice and took the derailment plate off as I couldn't see a way round of fitting the Dispenser Assembly to enable it to be kept it on. Click here to see the picture of how I fitted it.
Removing the derailment plate is a pain in the backside, plain and simple. By using a Black & Decker Wizard with a cutting wheel, a hammer, and a couple of beefy screwdrivers I got mine off fairly cleanly. All I would say is to take it carefully and don't smack your rear sprocket too hard as it could bend it! Its worth taking your time here to make sure your do a clean and careful job. I spent time on each rivet head ensuring that I ground it back to be flush with the sprocket.
I removed the white plastic lower chain guide and drilled four holes, two inline with the bolt holes and two about 1cm below each of those. This is to allow two cable ties to be passed through to secure the assembly. I fitted the chain guide back and positioned the assembly securing it in place with two white cable ties. This provided an excellent secure way of fitting it.

5. All that then remained was to connect the Delivery Tubing (item 16) to the RMV. I used the super glue to fix two of the Dispenser Mounting sleeves (item 15), and a bit of the Delivery tube conduit (item 17) under the swinging arm.

6. All that remained was to fill with oil and prime it.

7. Job done. Click here for the finished picture!
