for your 04 ? stock 130,try135 main, stock pilot is 70 some use 72.5 or 75....

Yeah, on my 38's I ran 132.5 main with 72.5 pilot. 95 gram spring.

I totally forgot to say that I'm running dual 44
So the jetting factory recommended won't work I've red the carb spec fourm and the main everybody is running 120 so I bought that one, I want to start rich when I'm jetting right? So are the bigger the number of the jet means it puts more fuel in?

Try this:

Brand = Mikuni
Model = OEM
Size = 44mm
Quantity = 2
Main Jets = 117.5
Pilot Jets = 122.5
Needle/Seat = 2.0
Springs = 95g
Pilot screws = 1.25
Main Screws = 1.00
Manifold crossover blocked

Jet-World.net has the cheapest price on Mikuni jets but they're a little slow on shipping.

Also read this tuning info and it will help a great deal.

My SJ was close to those specs a few years ago and when I ran OEM dual 44's mine ran awesome with:

Mains 110
Pilots 117.5
2.0 needle and seat
95 gr spring
24-26 pop off
EDIT/added: This was with the OEM manifold with crossover tube open.
I would block crossover tube if I were you.

?

Manifold crossover blocked

...whats that...i have a protec intake if that matters

You don't have to block the intake manifold crossover; it's just there to promote a smother idle quality for stock engines.


It does improve the signal to the carbs once it's filled with epoxy and makes the jetting a bit easier.

Im sorry I have no idea what you are talking about, could you start from the start lol

pro-tech intakes dont have crossovers ( atleast mine doesnt ). But the crossover is a "tube" that goes between the 2 channels, basically connecting the carbs. All stock intakes have this crossover.

Here's a Pro-Tec intake with the crossover passage on the left side and here's an intake filled with Devcon aluminum liquid epoxy on the right side.
