kinda tricky but not really. larger dellorto's (as in 15.15 and 16.16) have a 21mm clamp mount and the bing is 20mm clamp mount. The largest bushing available for the SHA is 19x21. Basically you do make it work by making your own bushing. Some 14.12's have 20mm so they go right without the bushing. Or you could a dellorto manifold.
