If I ride my bike, with breathers vented outside of TB, in Cal. what are the chances of getting ticketed and what is the penalty?
Also what other states have similar laws?

 

 

Chance of getting ticked here is zero.... there is no MC annual inspection, cops couldn't care less.

Fact...plus we can white line while riding our non-inspected sleds! YOW!

 

No chance.....there is no annual inspection, and as long as you are riding/driving/registered legally the police/ DMV don't nitpick your ride. Very ironic though since California is HARSH on anything else air quality related......cars, manufacturing, even law mowers are highly regulated for "clean air" .....though they don't inpect lawn mowers....yet

 

It is a 10k Federal fine for modifying pollution controls on a vehicle. Not exactly sure who it applies to however. Here in VA in my area,our state inspection looks for them and as long as they are there, he is OK. However, even this is spotty. My inspection the other day was me showing the guy the lights worked. Then he walked a 360 about 4 foot from bike and pointed the flash light at the bike to show he was taking it all in. Sorta guess that works for me since I take care of my stuff.

Not to change the course of this thread but i often wondered if there is demonstrable benefit to routing crankcase vapors away from the induction path.

Clearly getting cooler, cleaner air is preferred, but given how little oil actually escapes (not much, if any, of a loss between oil changes), I just wonder if there is a noticeable or demonstrable benefit ... other than theoretical.

Disclosure: On my two current Harleys, one vents to the TB induction and one does not - but they are two completely dissimilar bikes so no basis for comparison.

 

Serves no purpose except for the tin men's pocketbook. The air drawn in is only being pushed by atmosphere pressure. To weak to pull in oil. That falls out.
The crud you see in throttle body is behind butterfly. That is the last shot of dried up fuel from the injectors that is left ever time you shut off engine

 

165,000 on my '00 FLTRSEI still vented into the throttle body. No issues.

 

Technically crank venting (and EGR more specifically) into the intake does reduce combustion exhaust temps, but only marginally because now there's a certain percentage of noncombustible "stuff" in the intake stream.

I like to redirect crankcase venting to atmosphere wherever I can, just keeps things cleaner and less oily in the intake and carb area.
