I have a good selection of the mikuni hex-type jets. Now I'm trying to renovate an '85 that has the slotted type round jets. If I change the needle (that the main screws into) can I change to the hex-type jets? They seem to be different lengths and the 'baffle' between the main and needle are different. I'd hate to have to lug around two different sets of jets. Thanks for your help.
