That depends on the modification. A turbo alone may or may not improve emissions, it depends, which is besides the point since crewing with the emissions system is still a federal crime, albeit one not really enforced.

There's no huge gray area here. The DMV explicitly states a SPCNS vehicle, in this case a motorcycle, can't be something modified from it's original design. It has to be unrecognizable as a production vehicle, can't resemble anything, and a Honda with three wheels is still just a modified Honda, and fairly recognizable, even if the inspector hasn't yet seen someone take a wheel off a Honda yet.

Yup... That's what the DMV stuff says.

It's already as clear as it's gonna get as per my last post. If it resembles another production vehicle, even if it's modified from it's original design, then it's not SPCNs. It doesn't get as clear as that. A Civic with three wheels does not get a SPCNS reg AFAIK, since it's still just a modified Civic.

Not AFAIK. The ref will look at it, maybe comment on the interesting Honda, and designate it as a modified 199x Civic, provided the modifications are safe enough as per a CHP inspection. It won't be a SPCNs unless the body doesn't look like anything else in production, ie a tube frame or similar.

It must be nice to have such a loose system over there, but unfortunately, it;s pretty strict here.
