When talking in terms of replacing the air intake I have decided that the 90 degree is the way for me to go. When looking at two options available from Fuggin and L&M though they look really similar (I'm talking about the 90 and intake assembly) there is one glaring difference and that is the breather filters supplied by L&M. Fuggin doesn't have that included.




Why are they for? If they're not necessary, why does L&M include them?

I'm worried because I live in Chicago and I'm riding on days like today where it's 32 degrees outside. If these filters are used to prevent condensation or water in general from getting in my engine, maybe I should have them?

I'm confused and neurotic.:confused:

I don't want my quest to customize my bike to end in me destroying it!!:D

Scratch... I put the L&M adapter system on my Fury. Those two small filters are for the case breather. They are tucked in behind the cover you are showing... wish I knew where the directions where but I installed it before the move... but it was simple to install... just have to use your head with the install and cut and slide a small piece of the smaller diameter tube to put in the larger diameter tube.
As for your concern for your temperature outside, with a good EFI controller you should be able to keep the fuel/air rich enough to be safe. I use the FUGGIN EFI controller which is really easy to change once you understand the modes and what they do... I am still learning... :)
Hope this helps you in your quest... :cool: Stay safe and enjoy what ever you decide to go with.

Thanks CB.

Here's the question then, I bought the Fuggin 90 degree adapter. It doesn't have those filters. Everything else looks identical (aside from the throttle body cover).. so if everything else is equal, why wouldn't Fuggins adapter have the case breather? Or when you say case breather, you mean exactly that. It's a breather for the case surrounding the throttle body?

Sorry for being thick, I'm just trying to understand this as thoroughly as possible.

One of the reasons I went with the Fuggin is that it installed just like the stock. No mods needed to be made to the intake. I wasn’t sold on the extra filters.
I agree. If you recall when you took off of the stock airbox, there was a little clear rubber tube at the bottom. It seemed that that tube accumulated moisture in it, at least mine did. The Fuggin setup, though really straight forward, made no accommodations for the removal of that clear tube.

Now for all I know, it doesn't need it, I'm far from a mechanic. And maybe that little tube at the bottom of the stock air filter isn't needed with a modified setup. OR maybe it is needed and L&M knew that and that's why they added these breathers to their setup.


Don't know and that's why I'm asking.

Copied from http://www.myvtx1300.com/

"First of all, the pair valve and all the hoses you would remove are installed on your bike for EPA/smog purposes. Removing it won’t hurt your engine. The pair valve, in general terms, sucks air into the exhaust port to perform its EPA function. This makes your exhaust sound poor during deceleration. Sometimes, the pressure is too much and you’ll get backfiring. But mostly the exhaust sounds like air is trying to enter your exhaust also known as fluttering. This deceleration affect is more pronounced on bikes with after market pipes. But you may even notice it on a stock exhaust. Once you complete this pair valve removal modification, you’ll notice a much crisper/cleaner sound coming from your exhaust. "

I read the instructions on how to do it on a vtx1300, seems easy enough and I'm probably going to do this for other reasons, namely my backfiring problems.

But are those breathers for EPA and that's it? Cause if it is, I'm not longer concerned about them...

Screw the EPA , they are to filter out any debri from entering the heads / threw the exhaust , as the factory air box uses the factory paper filter . They are there to protect your motor , Unless you decide to use the birgly plates and remove the system , as you just stated . Loud pipes Big air love it

Scratch... I think you are on the right track... I did not do much research about them before you asked and after I sent my thoughts... that is what those tubes are doing... just EPA shit but since I live in lovely SoCal I am not sure if I am just going to remove them... sorry for the miss lead earlier just did the job... have not looked at Fuggin's set up yet... Hope it all works out.

Does anyone know if this wil cause me to fail?
Probably. A simple, quickly reversible (come emissions-testing time) solution to the PAIR-valve/decel-popping problem is to go to your local ACE Hardware or bearing store, purchase a 9/16-inch (0.5625") ball bearing and shove it into the intake hose that goes to the PAIR-valve. Come time for the E-test, you just pop the ball out, hook up the hose, go do the E-test, then put the ball back in. Using a short (2-inch) piece of same-size fuel hose, I ball-plugged mine right at the PAIR-valve, keeping my stock hose for possible later use; outa' sight, outa' mind. Simple, huh?

Cheers

Blu-

Is this where you got your blockoff plates? Biglry & Bone's

I'm not sure if it's federally mandated, but I have emmisions testing in Illinois. Does anyone know if this wil cause me to fail?
Yea I beleive so . Not sure on the emmisions testing as its not required here in Texas . If you still have stock exhaust , I would think it would pass . Do further research to protect yourself .

I do not have the stock exhaust or intake. I changed that out with the V2s and Yes, I will read up on this. I have to admit, BarFury's solution sounds easy and more importantly, easily reversable. I've got to research this more cause I want to understand all the draw backs as well as the improvements.
