jetting specs for 89-96 - anyone?

Taffy · Dec 17, 2012

anyone got the specs for the early jetting written anywhere? all I can see in the first couple of owner's and part books are the individual part numbers and not what the specs are.

my info starts with the '98s

I will dig around and see if I can find or remember the specs for the '96 FE501 I once owned. It used the flat slide 38mm Dellorto with a K35 needle,33 pilot jet, 260 needle jet, air screw 3-3 1/2 turns out, and I think the main jet was a 185. I have the '89-'96 parts manual as a PDF file and it list all the stock specs. for each model.

I also have the 96 parts in PDF but the parts are just that: parts. the customer I'm dealing with has a PHM fitted when it should be a flat slide so he'll need a later spec jetting line up anyway.

can I have a copy?

Hi

From the 89-96 parts manual you can get some info to the std. setup:

ROUND SLIDE - 180MJ, AB365 Needlejet, 50 throttle, K32 needle, 52 PJ

FLAT SLIDE - 185MJ, FN260 NeedleJet, 55 throttle, K32/k35 ?? needle, 33PJ

bigger engine (501) - round slide, smaller engine (350/400) - flat slide.

I have here one flat slide from the 400-97, I can check and send you the setup that its there, or can sell you the carb cheap

and what cc might they be for Ned?

also, the 600 doesn't appear in the 89 - 96 book! so shall we say: 1997?

I have the jetting from my 98 600

But my carb is one 40 (round slide PHMBH), like all 600's I think, but is the one from your customer also one 40 ?

:cheers:

jtg_york · Dec 18, 2012

this is what I have for the 2000 FX600 I have. The carb is the PHM 40 and the stock settings are:

Main Jet 195
Needle Jet DR 270
Needle K 51
Needle clip post. #3
Pilot 33
Throttle 40
Float valve 300
Start Jet 45
Fuel Screw 1½ turns

I know there are some differences between models, I hope this helps.

Taffy · Dec 19, 2012

thanks for all the help everyone. if the 600 starts in 1997 well then I think that the later specs are just fine. the ignition changed a bit but looks like the same cam as the 501 so should be good with the 1997-2000 specs.

Hi

For the 97/98 FE there is are small dif: clip C2, PJ 40

You can allways play with DR272 and K35 and SJ40, etc.., but you know all that ... or did you forgot ?? :mrgreen:

I know all that.

me forgetful! tish! tish!

unfortunately Dell orto only made one width of needle and they all 'burble' due to being rich. I have had special brass needles machined for me 3-4 years ago and I've never tested them. never had the time.

Hi Zaga

I have another 600 here today and the needle is a K32. clip 3.

but your 33PJ doesn't make sense with such a large (55) cutaway? could it be nearer a 40?

Hi

Those were the specs that I got for the older bikes.

The ones I mention as flat slide are for the 350/400 bikes and the round slide are for the 501. I don't think that there were any 600 back then.

But even for the 501 the PJ is a 52, the 33 is for the 350/400.

Anyway the stock jetting of my 600 (98) is MJ-195, NJ-DR270, Needle K51, PJ-40. But they go leaner than that as you know. They go to NJ 35 and 33 with DR72 and DR274.

I think that the K32 on that 600 is out of place, probably ??

:cheers:

well this particular bike is a 1995 and it has a 38mm flat slide fitted.
185 MJ
33PJ
K32 c3
FN260 atomiser

just thought I'd add it to the pot!

got it running really swtt today with a 38PJ which coincides with my policy of going down one on the OEM specs. so I think that your 40PJ was right Zaga for sure!
