thanks, have to work out what carb it suits  , 40 or 44

[Hossamania]

I'm pretty sure that's for a CV 40

That needle you mention is from a CV40 and should not be in a CV44, some people say they do work but they are shorter and can cause the slide to get caught when the needle pops out the emulsion tube and does not go back in peoperly

This what used to come in the tuners kit when it was available

Here is a guy selling one on Ebay don't know what photo is about but he has needle listed as NBEL  B & 8 hard to tell

can cause the slide to get caught when the needle pops out the emulsion tube and does not go back in peoperly


This leaves the engine still at full throttle even tho you think you've closed the throttle.  Thrilling experience.

KOKO 3052, some are saying the needles are different lengths due to the emulsion tube being shorter or longer in the two carbs CV40 CV44 , as the larger mains are in the CV44,personally been told the CV44 are longer needle  , i have located a needle N8el here in Australia , but need it to be sent to my HD dealer from another Dealer, cheers

Not really.  The butterfly will still close.  The hanging needle will just cause a severe flooding condition...probably won't even continue to run.

    I have to laugh every time that chart shows up. It was my doing about 15+ years ago, one of the first things I ever did once I got learning a computer. I initially put it up on the old Head-Quarters site, and It took me a "Potty mouth" load of time to get all that stuff arrange, then poof! its public domain. Hind site being what it is, Just shows there's no proprietary info on the internet, or at least I had no clue at the time.

    As needles go, for a 44mm, a N72S is a good fit. But its getting harder to find what you really want.

CV44 needle length: 2.340"
CV40 needle length: 2.235"

If you use the CV40 needle in a CV44, I don't think the needle will come out of the jet when the slide is all the way up (although I've not tried it). However, it will be lifted about 100 thou more than the CV44 needle, meaning running on the rich. Could be good, could be bad, see what the dyno and your plugs have to say about it...

Wow so you are just guessing and actually have not tried it

I don't think - very apt

Unfortunately, this happens too often here. At least he had the decency to disclose that he had not done what he was hypothesizing about.

The difference seems to be 5 thou...not 100 thou.

[barny7655]

more like 105 thou, just over tenth of a inch, cheers

YUP.....my bad....must have run out of fingers.

[barny7655]

found all  parts , thanks to all , carb is back to standard,cheers barny

Circling back to close the loop...

N72S from CV40 in a CV44. Wide open slide, needle still in jet. Not even close to coming out. What a good guess, huh? (or was it a guess.....?)

[Hossamania]

How's it running for you?

[JW113]

Me? Would never do it myself. I figure there is a reason they make CV44 needles for CV44 carbs, and as stated, the CV40 needle will be way too rich as it would be lifted up way too far.

But if somebody else wants to give it go, be my guest! All I know is it will "fit"...

N72S the second longest cv40 needle there is.
Try a N86Q and change your shorts

[JW113]

Change shorts? The slide is not the throttle....

This is why this site is so great , when you want to rebuild items, like a CV44,  input comes from afar, one must remember one has to know there may be a fault before proceding  when one has a item CV44 in parts , one doesnt assume all the parts in the basket fit that item , CV 40, CV44 , we found the needle of all things, so different , when most other items would interchange  , lesson  is find the oringinal parts sheets, then procede from there , KISS , where this site does KISS , cheers to every one for xsmas , Barny
