EMISSIONS CONTROLS 

The 2 stroke engine for has been a large experience since before 1970 for many until late 1990's when emissions became something 

Now worh an uptick in new 327 Fuel Injected 2 Strole MX Motocrossers we need to look at limiting use & banning manufacturers from building these due to inappropriate emissions & further more with efficient fuel injection while voids kick start & spark fouling due to fuel mixture controls which are great yet efficiency ceases

5 TO 10 TIMES LONGER

Due to how they process fuel and oil, two-stroke (2T) dirt bikes emit significantly higher hydrocarbons, carbon monoxide, and exhaust smoke than four-stroke (4T) bikes. Because a 2T burns engine oil with every revolution, you would need to ride a 4-stroke 5 to 10 times longer (or more) to produce equivalent total emissions. 

Why the Emission Gap is So Large
The difference in pollution output comes down to the fundamental mechanical designs of the two engines: 

Two-Stroke: 2T engines don't have separate oil sumps for lubrication; instead, you must pre-mix oil directly into the gas. As the fuel/oil mixture enters the combustion cylinder, a portion of the unburnt oil and raw fuel escapes directly out through the exhaust port during the scavenging process. Because they fire on every piston stroke, they produce high unburned hydrocarbon emissions. 

Four-Stroke: 4T engines use a dedicated oil reservoir to lubricate the internal components and seal the rings, meaning the engine only burns gasoline during combustion. Because they fire every other stroke and have a more precise, closed-loop combustion cycle, they are far more fuel-efficient and release fewer greenhouse gases. 

Comparing Apples to Apples: 250cc vs. 250cc
If you compare equivalent, modern closed-course motocross bikes (e.g., a 250cc two-stroke vs. a 250cc four-stroke), the 2-stroke produces:

Up to 6× to 10× higher unburnt hydrocarbons.
Higher levels of particulate matter (visible exhaust smoke).

Higher carbon monoxide (CO) output per hour of runtime, though modern fuel-injected (TPI/TBI) two-strokes have significantly reduced this compared to older carbureted models. 

How to Mitigate Emissions on a 2-Stroke
While a 2-stroke will never run as clean as a 4-stroke, you can reduce its environmental impact by: 

Using a high-quality, fully synthetic pre-mix oil (like AMSOIL Synthetic Dirt Bike Oil).
Mixing at the leanest recommended ratio safely allowed by your specific bike's manual.

Ensuring your carburetor is properly jetted to avoid running too rich (causing excess spooge and unburnt fuel). 

NEW EMISSIONS STANDARDS & EFFICIENCY 

4 & 2 Strokes require a new muffler catalyst where clean Air exhaust outward then the remainder filters into a rock tray creating biodegradable stones

2 strokes should have a new mandatory fuel reservoir tank where you pour in oil & gasoline separately then it auto-regulates matching required mixtures you cna adjust with fuel injection or carbeurators for elevation & performance so you do not self mix like a 4 stroke

EV Electric Start with kick back up on some models. No fouling spark plugs ever 

4 strokes = more expensive to repair. More parts. 2 stroke = more expensive to operate. This equals out ownership expenses almost equal 

100-200 hour rebuilds for competition & 200-500+ rebuilds for not competition

CARBON ROCK DEBRIS TRAY UNDER REAR FENDERS

If shredded & safe for not burying the debris could be disguarded on a trail. This effect will see all Emissions translate to oxygen only. Clean air then debris rocks disguarded from catalyzed & processed emissions 

Simple bolt on attachment connects under rear fender with space for the tire in suspension contraction then integrates as a second muffler system
