Finally I have a CV carb on the way....I got one coming from ebay...and I've ordered the cables, manifold, etc, new from Zanotti HD....so I should be ready to install some time next week or by the weekend.

That ol'butterfly carb still works fine but I could never get the a/f mixture setting and slow speed jet just right...and I am long overdue for a new carb anyway. Plugs were on the white side after installing the new cam so it needed rejetting again anyway, so why not just finally upgrade...

So I am running a stock engine except for the Andrews EV13 cam....and I have the SE slip-on mufflers...and SE (K&N) hi-flo air cleaner....so I am thinking it should be pretty easy to get the carb matched up...

Just wondering what I should try as a starting point for the jetting. I have no idea what jets will be in it so that'll be one of the first things I look at. The guy who I am getting it from said he had it on a 95" with Andrews 37 cam so I am guessing the jets won't be right for my machine.

46 & 185 and might have to fall back to an 180 but being rich would be a safe starting point, remove the mixture screw plug before installing it. It probaly has a 46 & 190 in it and just my opinion and not in stone.

 

Thanks for that info, 1997bagger.

I have been researching this a little too...it looks like stock is usually 42/170 jets.

The nightrider website recommends 45/180 for a stock needle and 45/165 for a sportster needle, to start with.

I am thinking I'll receive the carb tomorrow so I will know for sure what jets are in it....I am under the impression that it has a sportster needle already in it when he had someone rebuild it and it may come with 48/190.

Your suggestion of 46/185 or 180 sounds like a pretty good starting point. I have a feeling I will need to get my hands on a few spare jets.

 

My 99 Softail seems to be doing well with 45 and 180. But, mine is stock cam, dragpipes, and K&N air filter. Yours with a cam change might want to go to 46 or 48 for pilot, and 185 for main. Just another suggestion. They really do not to seem to be to critical, as I have been riding for a while with the stock 42 and main 180, and although it did seem a little lean, it ran fine, and did not blister plugs. Sure runs better now though.

 

If it were mine I would start with a 45 slow 170 main with a sporty needle. The sporty needle will richen things up.

 

The sportster needle setup is a nice option as mentioned, there is alot of referance available in the search function of this forum.

 

I run the sporty needle on my bagger. With bigger jets of course. It runs great. I use the choke for 20 seconds when cold and get 40 MPG all day long.

 

40mpg would be quite low for my bike... I usually get 45 city and near 50 highway with the butterfly carb....I am hoping my mileage won't take too big of a dive with the CV+sporty needle...what cam and mods are you running?

 

As i stated I am running bigger jets. Jet size has a lot to do with MPG. You are running an EVO and I a twin cam with head work. So it's apples and oranges as far as MPG and our bikes.
