[QUOTE="Little Honda, post: 108374, member: 667"] Agreed, David. "Never touch a running system" is the saying. I discussed the problem of breathing twins with Ernst today on the phone. His opinion was similar to your added article. So I suggested - to check, if the crankcase volume in Vincent twins is so much smaller, than on singles - simply to add a temporary tank volume in the size of the standard crankcase volume, thus doubling it. This should show, if the twin engine under these conditions would behave like a Comet. If not, some more thinking has to be done... ps: this tank having no atmospheric exit, of course [/QUOTE]
