Banshee jetting on PWK 28MM Keihin carbs

[shudakeptquiet]

Hey guys, I need some help from the experts PLEASE:
I have a 2005 Banshee, currently setup with a Toomey T5 Kit (intake and their jetting on stock carbs), and a slightly milled stock head. I also just bought, but haven't installed yet, a timing plate which I will set at +4*.
I just bought these Keihins:

Seller says they're set up for stock pipes, although I can't imagine who buys Keihins for a stock piped Shee...

What jetting should I be at for my setup? Where can I buy the approprite jets?
If you guys could help me out I'd really appreciate it.

And, on a side note, it's March 14th...Happy Steak and BJ Day!!

Sellers can not tell you what the bike is jetted for. there are too many variables in the equation. Temps, altitude, rider weight, all mods, etc.

48-52 pilot, CEL needle mid clip, 148 to 155 mains.

Start fat, go from there.

OK, I can see that, thanks.
Let's see...
I live in South Florida, so no altitude what-so-ever (sea level), and temps average about 80*.

I weigh anywhere from 190-205, depending on the amount of suds drank that day.
Mods are T5s, uni filter with no lid, timing plate +4*, and a slightly milled stock head.
Thanks for the post Dajogejr, you are the man!

UPDATE:

Can't thank Dave (dajogejr) and John (RJATV) enough for their help and suggestions. SUPER good guys, both of them, absolute assets to the Banshee community!

Carbparts.com lists this as the standard jetting which I will assume I am getting:
Size Main Jet Slow Jet Jet Needle Throttle Valve
Standard
PWK 28MM 73R #135 #38 46JJ8 C.A.3.5

Here's my shpping cart at www.jetrus.com:
Main jet size 148 (SKU- KH 25) $2.89 USD
Main jet size 150 (SKU- KH 25) $2.89 USD
Main jet size 152 (SKU- KH 25) $2.89 USD
Keihin slow jet size 50 (SKU-k26) $6.09 USD
Keihin slow jet size 48 (SKU-k26) $6.09 USD
Keihin slow jet size 52 (SKU-k26) $6.09 USD
Subtotal: $26.94 US

This should get me close, right guys?
I figure I'll start around a 50 pilot and 150 main, and then plug chop and go from there. Sound good?

LOL, yeah it should sound like a great idea to you... it was yours.

Well, I ordered those jets, so I'll start there and tinker as needed. Too bad you don't stock them yet John, but you'll be getting enough of my biz shortly I'm sure!

Yep, that will get you close.

Do you know how to tune a pilot jet via the air screw?

Warm the bike up all the way....

Shut it off, turn the air screws all the way in till lightly seated. Turn each one 1/2 way out. Start the bike...wait 20 seconds, go for a ride, come back.
Turn the air screws 1/2 turn out further, wait 20 more seconds for the adjustment to "take" then ride again.

Stop when you get the HIGHEST idle.

If you end up with the air screws more than 2.5 turns out from the lightly seated position, put a smaller (leaner) pilot jet in.

If you have .5 or LESS turns out on the air screw, put a larger (richer) pilot jet in.

You have to make sure the bike is up to operating temps....and you wait 20 seconds or so between adjustments. They take about that long for the setting to "take"... Good luck.

Hopeing yall can help me out. Got these badboys installed and have about 1-2" of slack in my throttle cable?? The cable came, with the carbs, from a banshee with thumb throttle... I have a lot of play?? Any suggestions? I have the adjustment screw on the handlebars al the way out. HELP. I have so much play the carbs onl open 1/4 of what they should...

You have one of two throttle cables. One for a TORS, or one for a twist throttle.
Hit up RJ or one of the site sponsors and get a stock throttle cable for the thumb throttle WITHOUT TORS. It will work....promise.

I thought the SAME thing bro. I called the guy I bought it from, he owns a dirt bike shop, and asked him that specifically. He told me that he himself removed the carb and cable from a running banshee with a thumb throttle. Now I just have to ask myself if I believe him...

In the mean time, my buddy fastLANE and I have been trying to figure it out. We ran the throttle cable ball UNDER theclip and then attached it, This made it almost perfect with adjusting the cable adjustment and carb adjustments out pretty far. Bike starts and runs/sounds good. It WILL NOT hold an idle without the slightest bit of pressure on the thumb throttle!?! If you just barely touch it, it's good(well, has a fast idle, but runs), but the second you let off it the bike stalls. WTF is that about?

Dave, you are the man, I hope I'm not pissing you off here...thank you for all of your help and advice.
