Exact size of dellorto bushings

Im going to design some intakes and wanted to know the exact size of whatever dellorto bushings anyone has. such as if someone has a 16 id and 21 od bushing its not exactly that size. Im mostly looking for digital micrometer readouts such as 15.92mm id. and 20.96od

Hundredth's of a MM are no going to matter anyway, that is the reason you have the bushing to begin with. It would be best to machine to nominal size.

yeah plus its plastic and wafer thin so its not gonna be perfectly round, especially if you go clamping a mic on to it.

if your making an intake for an SHA you'll probably want to do 19 mm that is the most common size

Re: Exact size of dellorto bushings

Shim is only there so the clamp on the carb can actually grip the intake, for a goodly seal you need to use a oring at the carb to intake union.

5/8 x 13/16 x 3/32 oring is a great fit into the 14mm carb sizes, 11/16 X 13/16 X 1/16 oring will suit the 15mm SHA.
