HD200 Emisisons control

[fiddlercrab]

A few years ago I took my 2009 HD200 into to shop for something, and the mechanic casually said that he took off the emissions control and that it would run much better, and it did. I now have a 2014 EVO and sometime feel a slight hesitation now and then. It only has 400 miles on it. My question is: how difficult is it to remove the emissions control?

Can't tell you about removing the emissions equipment, but how did it run better?  Mine runs perfectly up to about 75 mph.  As far as I know it still has the emission control parts, but I never actually looked.

I have an 09 HD also, what is the emissions equipment and wher is it located? Any benefits for it??

Benefits if you're running fine.
Nope.  Even fully pulling it won't gain you much.
If you're not then I think most gains are from removing what were leaky vacum stuff, but others will differ.
I've thought of pulling them just to simplify the bike, but really they haven't given me any flak and maybe, just maybe they do make the air a tetch cleaner.
https://symforum.com/index.php?topic=2413.0  Is really the only smog fix that you need IMHO.  This is just fuel venting, but if it messes up due to any number of reasons it dumps fuel in your oil, potentially a lot.

The article does link you to the other stuff, but the pics are long dead. 
If you're interested in the pics I nabbed 'em before they died online cuz I'm funny that way.  PM me a contact and I'll figger a way to hook ya up.
Of course actually removing your smog stuff would be an EPA violation so this is strictly for intellectual exercises and off roading purposes

Hi Guys,

I followed these instructions to fix some issues with a HD200 recently.  The initial problem was flooding that prevented a restart after a successful run and cool down.  The final problem that clued me in to the EVAP issue was fuel spilling out of the airbox.

It's been almost 8 years or so since I did mine, If I remember correctly all it required was venting the tank straignt down opposite side of the exhaust, and capping a vacuum port on the manifold.  Gives you the same results of removing the whole system minus the weight savings.   Problems show up when the canister is full of gas and can not breathe.
