I have a completely stock 2007 America. I am just now at my 500 mile service and am finally going to be putting on my new exhaust, etc. However can someone please check my assumptions/numbers.

What I'm planning on doing:

Adding new, completely straighthough TORS.
Installing Uni air filter.
Removing snorkel and install Polaris Bellmouth.

Question about the numbers. First I am going off what I've heard here on the forum that the 07 865 America has stock 40's.

Dinqua's (Pat's) Jetting Calculator Settings:

TOR (All Baffles Removed)
UNI Single Filter (Airbox not drilled)
Snorkels (All removed ?? I'm only removing the top what others are there on the TBA?)
Elevation (Sea Level)
Needles (Stock)
Pilot Jets (****42, there isn't a 40)
Needle Shims (None)

This gives me 135. Now the big problem I guess is that his calulator doesn't accomodate for the 40's. I have ordered 135 main jets as well as 132 (as going from 45-42 decreases jets as does going from 48-45 I assumed).

Does this sound okay? Should I be looking for anything else possibly even bigger pilots? I haven't had ANY issues with performance or flat spots on this bike at all.

Cheers,
Andy

I don't know the answer, but why not just put 42s in it?

I see your point, but what exactly would I gain by doing so? Conversely might I screw up performance by not doing it? I guess I can just wait and see what happens.

40s or 42s should be fine. You'll have to adjust the idle mix accordingly, but either one should work. More turns out w/ the 40s, less w/ the 42s.

If it were me, I'd stick the 42s in there.

My '02 America had 2 more baffles inside the airbox aimed at the intake manifolds. I'd imagine later models would probably be the same.

Well she is up on the jack as we speak. I'll be installing the remainder of my upgrades tonight and I'll report back how the 40's work out. I hope I won't have to put the 42's in only because I'm planning a road trip for next weekend and that might be cutting it a bit tight with regards to shipping.

When I put the new air filter in I'll also look for those other two baffles you mentioned.

Well I had enough time to fit the roadster screen, the new pipes (incredibly easy install), new Uni-filter (snorkle still in) and a light bar, but I never had time to put in the jets.

I rode the bike about 20 miles like this and it certainly sounded wonderful. The performance seemed ok, possibly a little flat on the mid range, but after only 20mi I'm not quite sure. I had to give her up to the dealer for the 500mi service so we'll see if they have anything to say.

The mechanic at my local shop loved the sound of the pipes. I hope he can make some solid recommendations on the jets as well. I'll post again when I know more.
