Your right about Calif. "speicals". Only now, since 2004 you can't build a "special construction" unless you use for example, an S&S motor, that has fuel injection and a non-tamperable exhaust system. And, if you did, you'd still have to camp out overnight in front of the DMV and try to be one of the first 500 in line to get a "building permit". If you don't obtain one of those "permits", you're out for another year. Basically, it all means no more Linkert carburetors out here, unless you have an old original title to build from, and then you don't need one of the special permits. (This is where the CHP steps in and will occasionally, out of m/c brotherhood and prevailing conditions, sign-off on a re-pop motor as long as it's in the frame an old titled machine you're trying to get registered.)
As first announced, the EPA rules seemed too extreme, with their one kit bike per lifetime provision. As it turned out, the Calif. Air Quality Board got more extreme than the EPA with intake and emissions.

So now, the EPA rules seem more in line with freedom and reasoning, allowing a one-time, emissions-exempt "S.C.", although you can't bring one into the state and get Calif. plates unless the motor and exhaust meet the new C.A.R.B standards.
Happy trails. Sounds like you'll have no problem getting yours registered. Thanks for the update.
