You didn't state the exhaust or intake components so it impossible to lend an opinion on how it will affect the bike. The 2007 or later bikes with a closed loop system can adjust the fuel mixture within a range, but if you need outside of that range you will need a tune. The real question is how far outside the self adjustment range will you be? What combination exhaust and intake will you be running?

wow. It is sad and just scary that so many people around this place spread this kind of misinformation and ignorance. It is absolutely not anywhere near fine running a stage 1 without some type of tuning. The new, or old style fuel injection on these bikes do NOT adjust for anything. A closed loop narrowband speed density efi is nothing like the mass air systems youre used to seeing in cars that are capable of adjusting to a point. The factory o2 sensors are narrowband and only see a very very small window in a very lean area. The sole purpose of the o2 sensors that have been added to these systems is to keep the engine running as lean as possible, as consistently as possible to cope with stricter emissions. They are not designed to adjust for anything. The only systems that are capable of this are afternarket wideband setups like a thundermax. I highly recommend a good dyno tune, it makes a massive difference if the tune is good. Not just power, but rideability, temp, everything. But what do I know, I've only tuned over 1k bikes, I didn't read my info somewhere. As far as the original question, the air cleaner is the easy part. Like others suggested I'd put the exhaust on and wait on the air cleaner. Could just pay the dealer the half hour to install.

Well, I'm not going to get into an internet pissing match, but while I made a pretty broad statement, it has been proven to me through dyno sheets that I have seen and through riding my own bike. Beyond that, my sig lists what I have on my bike: Stage One intake and Rush slip ons, and this setup, in my actual experience (not based on theoretic estimation), I am 100% sure that my bike runs better than it did before and I don't need to pay anyone to dyno it to sleep better at night. My plugs look good, my engine runs fine, and the EFI has taken care of the adjustments appropriately - most likely because I didn't do cams and all the other stuff. When I have the funds in the budget, I might end up getting a dyno tune down the road, as I know it will make it run better still. But for now I am sure that it is running well enough for my riding style and, more importantly, the engine is healthy.
I also ride with guys who have done full V&H/Stage One and TH/Ness exhaust and intake setups without a tune or remap and their bike run just fine, better, actually.
I know there are a lot more involved mods, and you will always get much better performance from a full dyno tune, especially if you've done a cam swap, etc. but that's not what the OP asked, he asked if running his bike for 3 1/2 hours with new pipes and a breather before having the bike dynoed would blow the engine. I am confident of the fact that it won't.
To say that I am ignorant or spreading ignorance because I answered the man's question with information based on my actual experience is ludicrous.
To the OP: you will definitely benefit from a dyno tune, but your bike will not explode in the 3 1/2 hours that it will take you to get home. That being said, you gotta make the call based on what you're comfortable with.
Again, I'm not into arguing on the internet, so I wasn't trying to pick a fight over this, just clarifying why I said what I did. And I respect all of your input as well.
Cheers,

If you are not comfortable, install the exhaust at your bro's, ride home, then change the breather at home before your tune then you're not riding that far.

You do not need a download or any sort of dyno work for intake and exhaust, the EFI will adjust just fine. Check out some of the info posted on the Nightrider website and read about how several magazines and HD have run tests on bikes with wide open air in and out, without changing anything in the map, with positive results.
My bike took a bit of riding to adjust and get rid if the decel popping when I upgraded the breather and pipes, but not too much. Just ride it and pay attention to what it's trying to tell you.

I picked up 10rwhp and 20rwtq having my car dyno tuned after intake/exhaust mods. And that was an increase from a baseline canned tune.

Whether anyone is for or against or whatever opinion on dyno tuning, really the highlighted above is what the OP asked, and I agree with this. We got a little off track with dyno tune discussions..
If you are not comfortable, install the exhaust at your bro's, ride home, then change the breather at home before your tune then you're not riding that far.

Dealer installed a PCIII before I ever picked it up along with a heavy breather and 2into1 pipe. I have over 50,000 miles. Yes it might benefit some from a tune but it ain't hurtin except it doesn't get the best mileage it probably could.
