Bonneville America Forums Forums Technical Forums Performance Mods Airbox Mod / Re-jet

I just did the 'Ole airbox mod and rejetted.
WHY DIDN'T I DO THIS THE DAY I GOT IT?
What a difference.
I do have a question concerning the air/mixture adjustment.
Here is what I have...
06 TBA, Mod exhaust, Mod airbox, Ai's + Snorkels out, 132 main jets(per Dinqua's jet calc), 3 turns out.
I started her up and no huffin or puffin or poppin, so I didn't do anything more to the mixture. I went for about a 8 mile ride. She gets going now.. wow.. No popping on decel, it is actualy very quite? Ran awesome. Maybe I was just paying too much attention, but it sounded a little "airy" out the exhaust when riding. I really don't know how else to explain it. Almost like the exhaust got more quite. If I am idling and snatch the throttle real fast, it will "bogg" for a split second. Is this my mixture? Which way to turn them if so?
Thanx in advance

If it's fine above 3000 - 3200 up to the rev limit, you need a litthe more gas at the low end, Try turning the idle screws out a little at a time and see if it gets better. If you reach 4 - 4 1/2 turns before it's perfect, you should consider a step or 2 bigger pilot jets.

I have no tach, and I haven't found the rev limiter yet. But yes, it did seem fine in the higher RPM's. So, Just work them out 1/4 turn at a time? Will i notice any difference at idle? Thanx Ed

My setup matches your exactly with the following exceptions:

- '05 TBA
- TOR longs
- 3.5 turns out when using stock idle mixture screws
- 2 Shims on stock needles
-- Used small brass washers found at Home Depot
- I synch carbs after every tweek using following method:

>$10 Carb Synch

I can't comment on "airy" pipes as I've never had that problem, but no "bogg"ing with my setup. So... give the shimming and synching a try.

i have removed three snorkels, have not replace jets and i have mine at 3 turns, i feel a little hesitation when i am at about 60 and hit the gas, from a stop i can tell the difference it will take out without any hesitation very responcesive, i am waiting to change the jets out till i get some of the out mods. done, i have a question about shimming the jets? do you raise the jets from their sets with the washers.

The shimming is done to the needles...

I have a similar set up also
05 Green TBA
snorkle & ai out
drilled air box
long TOR
130 main
3 turns out

I have no popping, hesitation, runs great. This is the way it should have came. I did notice when I modified the airbox it made the exhaust a little louder but thats all good.

Just be sure if you are getting off the shelf washers that they are the same thickness!
