Welcome to California - Well, not really!

Sounds like if you don't want to move out of State, there will be a lot of Tiny Homes around.

You start adding anything to a 2 stroke engine that adds back pressure to the exhaust system,the fun begins,DDEC engines burn cleaner than the mechanical.The few I have been around with catalytic converters (RTS) were dogs and the converters were always plugged ,84 years old the 2 strokes have severed us well may they RIP

If grabbing a used one off a semi-truck and deleting the muffler. Maybe setup it up where it can be used to pass the 40% opacity level test and then straight pipe it the rest of the time....

I'm not saying there's nothing to be worried about or that this will never happen,

BUT

here is a thread from 2008 about how CARB is about to push out all the bus conversions.  Maybe this time is different, but personally if I were in CA I wouldn't worry too much until it was actually being put into practice.

@fred - When you dig into the meat of this regulation it is draconian. They are hellbent on getting all gross polluters off the road. Phase 1 is underway. Sensors are being installed along port of entry and other locations where heavy vehicles travel. The sensors pick up and report via ALPR (Auto License Plate Readers) vehicles that exceed the allowed limits. This is 2023. Starting in 2024, they are going to start sending NST letters to all vehicles like ours that are not compliant and give you thirty days to go to a certified Clean Truck Tester.. https://ww2.arb.ca.gov/our-work/programs/inspection-and-maintenance-program/credentialed-hd-im-tester-public-list.
@Nova - I've not been around with ears to the ground on this issue since 2008, others can weigh in, but from all my research this is the final nail in the coffin, legally.

2023 we are safe, 2024 really gets questionable how long we have until we get letters; maybe we don't but I would not bet a cent on that bet. Or you drive down the freeway where they have the sniffers, then get a letter. Sure, show out of state plates but don't get sniffed too often; you'll get a letter proving you life out of state and just happen to vacation in CA more than usual. Sure, register it as a historic vehicle. Same thing as out of state. As long as you avoid detection, it works. 

If ever there was an example of big brother this is a good one.

Everyone knew for years that it was going to happen, Detroit 2 strokes have been banned for industrial use like in the oil fields and construction equipment for over 20 years in CA,they are not going to give anyone a free pass this time around.As Don said before where goes CA so does the rest of states and that is true sad but true

Clifford, this sweep cleans the deck of all off road use too. We've been focusing on the on-road portion but they are just as thirsty and drooling on the off road part.
Maybe I'm just dreaming now but the way it reads and confirmed by PSIP and HD I/M tester is non-ODB engines use the J1667 opacity standard tools and that 40% is the golden ring. I have no idea if 40% is just some BS threshold they state so it looks official but if none of the engines run under that that so what's the point.
I just listened to a CARB presentation and they stated that a properly fitted DPF will result in 1% opacity and if not then something has a crack and leaking. I'm going to call some testers that do PSIP J1667 testing as that has been around a long time to get a hands on opinion on what makes the grade and what fails 40%.

If there is no way to pass via CARB and Clean Truck Check, then two paths may work. 1) Register as a out of state vehicle. 2) Register as a CA historic vehicle using DMC Form 17 A.

Scammers are going to make a lot of from this ,the 2 stroke design is a nasty engine for emissions,better start on another plan Don,tier 1 was the best anyone ever did. They never spent the big money to try and design a EGR system for the 92 series and none of  the add parts on from a junk yard are going to work on a non EGR engine.The non EGR 4 stroke engines are in deep trouble too in CA

Not really, Most of the country considers California to be the land of granola. Fruits, nuts, flakes, etc. There are many things about the left coast that are considered to be very poor ideas indeed, and a number of things that nobody in their right mind would consider.

I don't think CA will ever ban RV travels for out of state travelers lol they will hit you with fee at the fruit check points for that old DD

Most of the stuff becomes federal EPA rules for emission control, the states then do have to regulate some of their rules all you need to do is look under the hood of car and the price tag  .CARB is not a favorite of mine but they have cleaned the air in CA now you see the mountains anyway

Maybe put the fruit/nut check on the other side of the Freeway?

Don CA has had the J1667 (snap test) for 40 years,the 3406 Cat 425 hp smoked like a train under a load but would pass the snap test.
The PSIP test applies to all diesel trucks when the engine has so many miles in service, I forget but 3 to 400,000 miles

Going to call some to get their opinion and experience passing these old 2 strokes against the 40%. Nobody has posted anything specific if this is even possible or just pissing upwind. You'd be one of the most knowledeable on something this detailed on emissions and CARB.

My father was a UK consul in many countries, and his cars always had an oval CD plate next to the number plate;  with that magic CD plate we never stopped at borders in pre-Schengen Europe, and any parking or traffic violations were automatically dismissed.   I wonder what the California requirements are for diplomatic vehicles?
