Hi Guys

I was bought a vsystem Scottoiler for xmas ( dropped plenty of hints for one ) and was thinking of having a go at fitting it myself the only problem being I dont know what to look for when searching for a vacume point.

I would be greatfull if someone can give me a clue as to what I am looking for

Any help would be much apprieciated

ps

All the best for 2012

You need to find a convenient 'hole' in one of the inlet ports between carb and engine - hopefully there will be a plugged hole in the form of a screw in all four inlets that would normally be used for checking/balancing carburretors - you might need to obtain a threaded hollow junction tube (usually brass) if it doesn't come with the 'kit' (matching the thread of course). You can then use this to attach your flexible vacuum supply tube.

I have recently fitted a V-System to my VFR. The Vacuum tube on the VFR is located on the right hand side under the petrol tank. As yours is a Honda it might be in the same location or close by

as others said there should be a screw in each of the inlet rubbers between carb and engine you would remove one screw and replace it with threaded section that should be supplied with the oiler kit

Or you could tee into the vacuum feed to the fuel tap?

wouldn't do that myself - them vacuum petrol cocks cause enough trouble on their own if left standing.

Never had a problem myself and the tapping is already there?

glad to hear it - do you mean the tapping is in the manifold or the fuel tap?

There,s already a tapping to the cylinder head and a tube to the fuel tap. Put a tee piece in and fit it to the oiler.
