Default Not a Sporty Carb..but CV

OK, So I have not measured it yet, but it apples to be the same sort of size and look identical from memory..

27088-95

Got a new CV carb here, trying to find out if it is basically the same as my 04 or 93 Sporty carb, with just minor jetting changes..will hang on to it if it is the same carb body with different jetting and needle etc.

Any one got a clue ..or is it a bigger carb...seems to be off a 95 Fatboy or similar from what i can tell.

Likely still a CV40
Just jets and needle diff
There were some 44 and 51 SE carbs but would be marked as such

It's an HDI Dyna carb used from 1995-1998 with a factory 1.80 main jet, .42 slow jet.

Thanks, for that, not yet popped it open to check jetting

Looks identical (from memory!) to the basic CV40, but wanted to ask,

Measured throat yesterday and yes, 40mm at butterfly end, so yes, very likely a standard CV40.

Thanks

Yes, I can confirm those jet sizes, and add that it has a NOKR needle

Gave it a clean up yesterday and fitted it with a 40 slow 170 Main and the original 883 04 Needle. Looking on the Sportsterpedia, I think I should have put the 42 Slow Jet.

Fitted CV Perf IMS and Idle stop adjuster too.

Back on the bike today and fired her up. Not got oil tank fitted properly yet, or back end built , New tank on order but not yet arrived. Hope that will arrive this year...

Did your throttle cables fit correctly? Some of the BT CV carbs have a different throttle cable mount which alters the spacing between the cable & the throttle cam.

Yes, they seem to ...looking at the two carbs next to each other both carb and brackets look identical, but I did not actually measure the 'wheel'
I do have both the cable adjusters out to near on max..probably about three turns left on each one.
This carb is now on the 04 bike..

Out of the same box of bits the carb came from, there was also a set of new accelerator cables...they now reside on my 07 Sportster, the EFI one. Only thing that was different was the metal sleeve at the handle bar end..I had to bend it form what ever it was at to about 135 degrees..

I believe the difference was the spacing from the cable sockets to the throttle cam due to the size/position of the BT bracket...

Sounds like he had opposite problem. I had plenty of slack to make it fit.
