Neatly packaged and good instructions
Everything was like oem quality and worked perfectly. So far I am impressed. Great product and company from my experience. Thanks Sigma for even making a jet kit for these older classics!!!

Strong and sturdy
These work great on my 1980 xs, they hold up stock 38 carbs and pod filters no problem. Also made for really easy synchronizing with attached bards, once done just get some vacuum line plugs from a auto store.
