28 litre Acerbis tank
I have a 2005 640 Adventure and have managed to acquire a plastic 28 litre fuel tank. The mounting looks the same as my standard tank--and I can't see much difference, if any, in the internal cutouts (do I need to remove the SAS?).
The real issue I think I have is mounting the frame for the fairing/front screen to the top of the tank--there are no threaded inserts or tapped holes?. I could use self tappers and gaskets and probably seal it ok as the holes will be in "air" most of the time. However, were the earlier fairings mounted in a different way as there is evidence (rub marks) in the right place?
