resevoir mounting.
just run the tubing inside the frame down past the footrest bracket & leave a little slack to the swing arm.
I superglued a small section of the soft push in channel about 2" long underside of the swingarm to provide a secure starting point for the tube.
I used a scott oiler on a triumph trophy tourer, (one of the early ones of the new generation) & it worked great.
keeps the chain clean & crap off of the rear wheel once you have it set right.
