Wouldn't Interstate Motorcycles in Rolla mail them to you? If it were me, and it isn't, I wouldn't miss a chance to hang around that place, probably the best Royal Enfield dealer on the planet.
I just don't always have the time to roll up there is all.
Just to echo others, I kinda bit the bullet () and bought the five pack. Really, I guess 5 for $60 isn't that bad. Especially considering it comes with a million gaskets / o-rings (speaking of which are some of these extraneous/generic - only one of the o-rings matched up for me; gaskets were both different than what's on there).Is there a spin-on filter adapter made for the UCE? That might be nice. Especially if it could be had with a Chevy small-block filter. Might be a little big, but they are cheap.
