Pilot Air Jet P/N 0949334001 - Need One!

[SamLack99]

Maybe my 'Google-Fu' is weak?

Maybe I'm just tired.

Whatever...

...I cannot find this part:

Pilot Air Jet part number 0949334001 (170 <-- Stock size for my bike)

I managed to order the last 3 from CMSNL, but need 1 more.

Help!

Do you have one I can buy from you?

Do you know where I can buy one? (Preferably in the UK).

Do you know if there's an alternative part that will do the job? (it's gotta be a 170 as I'm trying to return the carbs to stock)

What does the '170' stand for anyway?

I've got 160's, can I drill them out to 170?

Help!

Once I've got this part, I think I can finally put my carbs back together =)

I'd put in the 160 and see what happens. Most likely it will be just fine.

They look like Mikuni B42/55. Check the dims, should be available at Allens Performance.

It's recommended you don't drill them out but you can. Wire sized drill bits will help out but you need to figure out the size. I've been known to drill them out. Mainly pilot jets.

170 is a number that the manufacture uses to identify the jet size - they have no rhyme or reason and the different manufactures don't use the same numerical system...

Thanks buddy, I'm pretty sure it is a Mikuni B42/55 I'm after.

I looked at "Allen's Performance" website, they have them, but only up to size 100.

I've contacted them to see if they can get size 170.

Of course, if I was in the USA, it'd be a piece of cake.

But, I really don't want to pay $20+ for shipping, unless I have to.

We'll see...

Did you try nrp-carbs.co.uk ?

You really shouldn't bother as it's not nearly accurate enough. Drill bits do not create an accurate sized hole & if you drill out 4x jets you will have 4x different sized holes. The difference in a Mikuni main jet & the next size up is usually 0.02mm, a precision tolerence that is well outside the capability of even the best drill bit & drilling method. Neither should you be poking them with a wire, a scratch in the bore surface, especially in the smaller sizes, can be equal to jumping 1 or 2 jet sizes.

170 is a number that the manufacture uses to identify the jet size - they have no rhyme or reason and the different manufactures don't use the same numerical system...

Mikuni numbers reflect a flow rate, Keihin numbers reflect the actual diameter in mm.

Yeah, haven't heard back yet...

Just heard back from NRP-Carbs - Seriously impressed by their rapid response time.

And unfortunately, they only have 180 and 160 **Argh!**
