I can't get my carb's tuned properly with exhaust and pods. ):

[natemoen]

The jets we use as air jets are call "Mikuni Small Round Main Jets". The jets we usr as main jets are called "Mikuni Large Round Main Jets". It just determines the size of the head of the jet I believe, I do not think it changes anything in the metering orifice.

HA ha ha ha........nate hates this chart but I don't care.....

Yea....well I do too, as it's MOSTLY wrong

OH MORE INFO AGAIN!

The mains I got looked more like main air jets... like they are smaller in overall outer diameter than the oines I replaced and they are the exact same size as the air jets, but with a smaller hole obviously...

The plastic bag they came in said MIKUNI MAIN JETS on them and seemed official...

Maybe they meant main AIR jets???

Thanks for those links though!

As soon as I figure out what sizes to get next I'll order from there... Fast shipping??

That is one of the problems when you are making major changes to the system. You really need to buy a bunch of different jet sizes and work through the sizes as you tun until you get it.

I am starting to realize that. haha

I guess I figured I magically get it perfect 1st try...

[Dylano*]

Have you looked HERE?

I have NOT seen that! Thanks!

So according to that, I should go UP FOUR main jet sizes from stock (3 for pods, and 2 for opend headers minus 1) and UP ONE pilot jet size?

Does that seem OK to everyone?? (:

I wanna order jets and get this monster rollin!

That jet must be gold plated for $16 for one jet! I paid 2.50 per jet at a dealership for the genuine mikuni pilot jets. That add also does not say they are genuine mikuni.

The add also says that it is a stock picture and not necessarily a pic of the real product.

PILOTS

MAINS

[natemoen]

It is $16 for all 4 (free shipping)

in the description it says "Brand: Mikuni"

If I recall correctly they came looking identicle to the pics. 2-2-2-2 pattern

2-2-2-2 is not correct.

[natemoen]

My bad, didn't see that one hiding down there!

Great info, thanks, that is now bookmarked (:

So does anyone think I should just go back to one over pilots or bigger?!?!

You say in a 2-1-2-1 pattern... :/

THESE are the jets currently in the bike, 2-2-2-2 pattern, they SAY they are mikuni, are they imposters?! haha

But you must remember, the MAINS are part of the equation. IF they are too small, then you could try going up in the pilots. I think that is the problem you are having now. Go up 2 sizes the mains, re-check the floats levels(with a tube on each carb, with the carbs level in a vise), and start with the screws out at 1 1/2 turns.
I almost always start with the idle set a little high so it will not stall when doing the first adjustments. as it gets a little better, you turn the idle down and keep going. For a "new" set of carbs, it can take two to three hours to get them dialed in.

I've been under the impression that the mains only matter when under HEAVY throttle, like 2/3 or more.

I can't even make it to 1/2 throttle it seems like!

Look at the 3rd post, the UK chart.

Ray, the mains don't even enter into the equation at idle.
