just some food for thought
I made a delivery tube arrangement which takes the pipe alongside the clutch cable past the g/box sprocket cover (SK1), and puts the oil onto the side of the g/box sprocket itself. A home-made bracket on the clutch mechanism bolts holds it there.
The idea was that it's sheltered in there and so the oil doesn't get blown about and most of it miss the chain.
It seems to work fine, though it's only really practical in this form since I have an aftermarket sprocket without the rubber damper ring, so can put the feed pipe right onto the side of the sprocket.
A possible alternative could be to put the pipe to deliver onto the chain as it leaves the bottom of the sprocket. Maybe someone might like to ponder this?
I can turn the delivery down pretty low, the chain is nice and damp, but very little gets onto the back wheel, just a few spots after a hundred miles or so, and of course it uses much less oil than otherwise.
Just a thought.
Bottom line though is that however you do it, Scottoilers really do take so much hassle out of keeping the chain in top nick........and in case anyone thinks what a wonderful invention it is, my Triumph Trident of 1975 has an oil delivery pipe to the chain teed off the oil return to the tank (dry sump), with an adjuster screw just inside the filler you turn with the dipstick to get the flow you want (and I'm sure earlier bikes had similar things too!).
