Perhaps this will not happen when flex mount kits are adapted for SU's but I have encountered many people who loathe the double O rings for Webers. My solution was to buy Mikuni (44mm I think) flex mounts from Malvern Racing, do some minor alternations and fit them to the intakes--they have worked fine for thousands of miles. Webers are extremely sensitive to vibration and mine practically float out there in twin cam heaven far away from the evil mechanical humors of our beloved engine.

The fancy double wound washers are called Thackeray washers. If you tighten until you leave a small gap between the coils you get the required amount of flexibility. If you tighten too much you are essentially going back to the rigid mount that causes the problem in the first place. You can be reasonably tight in terms of a non-leaking seal and still be able to grab the carbs and move them up and down a fraction of an inch. For the Thackeray washers the recommended gap between coils is about .040 [inch]. Use Nyloc nuts so the setting doesn't change, of course.
