I love my cv carb. Easy to work on. Set it and forget it.

I have the CV performance velocity needle, just haven't installed it yet.
I was going with 46/180 set up next. Might as well put the new needle in.

Any carb attached to a Knuckle, Pan, or Shovelhead.

You will like it. Start 2 to 2 1/2 out from lightly seated on the low speed screw.

What exhaust and cleaner do you have? If you have a little blurb blurb once in a while at idle get a 45 idle jet .

Also If you know this guy tell him to tighten up the rear pipe, it's quite loose.....

To heck with the crank pin and the oil pressure, in normal riding the engine doesn't spend that much time at idle and I would kill for that sound. It's an 80 cubic inch with 10.5:1 heads (ported and polished) Super "E" carb and an S&S 561 cam. In the comments under the video he said he tightened the pipe.

Question: I have a 2000 sport 883/1200 with #25648-91 se cams and se slipons, lollypop baffles, nice diy A/C, 6800 RPM Ing. module and it sounds pretty good but not like I would like. Got any suggestions besides, if it ain't broke don't fix it
PS: it has the stock 883 pulley's and will do 80 in 3rd gear like a scalded dog!

Samson slip-ons and a mesh bug eye air cleaner. While I am waiting for the new main jets to arrive, I put the 46 idle jet in and took a ride. I think I found the sweet spot. It ran like its old self again only better, thanks to the new carb.
