Mongo, did your dyno guy recommend any changes to the jets?

 

[Mongo]

yeah he said I should probably put a bigger intermediate jet in right now it is a 31 said I should go to 32.

Yep, but I've never seen a 32 jet. Next step is a 33. Should fix that fuel/air curve real nice for you.

It came with the .032 in it.

This shows they make it. I heard the same thing from the guys at a shop here.

It should even it out and not be so hard on the motor.

I'll be damned!!! I just checked the new S&S Catalog and it does list them now. I'm posted it many times here showing they didn't list a .32.

Very good then.

Any day you learn something new is a good day.

Where do you guys get your jets? Seems S&S does not allow price advertising... :bang:

I get them at just about any custom bike shop. S&S is very popular in the custom arena so most will have them for you. Seen a lot of them on eBay also.

I have a large bag of them collected over the years. They don't wear out.

Thanks! :2thumbs:

so reading the a/f/ ratio, when the line falls below the 13 to around 12 thats lean and I guess the other way is rich. just want to make sure I'm reading it right. thanks guys

The larger number is air and the smaller fuel. Most motor guys like 13.5 - 14.5 for the V-twin.
The graph above shows it awefully lean on the intermediate jet so thats why the discussion of going to a larger jet.

So above the line is lean and below is rich.

I need to get a jet kit

I guess I don't know how too read it. how it looks to me is between 3200 to 4400 the line is below the dotted line. Am I looking at that right? If so, you said belwo is rich.. what am I reading wrong.

You are reading it correctly but you need to understand how the two jets work.

The intermediate works up through 2500-3000 rpm. The main jet starts at about the 2500-and merges in to take over above 3000. But this can be adjusted by the air bleed.
Anymore and you have to read the S&S carb manual!!

what do you have in there for a main jet?
