Re: CV carb on my 1953 pan

Post by griffin49 »

I notice the comments regarding a CV on a 74in Pan, what about the smaller CI pan, same jetting? I put a 98 CV off a Dyna and may not have it dialed in right. Hard to start cold or hot, but starts great once cooled off a bit.
I also know my intake is taking in some air, any suggestions on best rubber gasket to use? Have seen some that are flat, better seal or stick with the stock ones?
Any help would be appreciated.

GRIFFIN49-

Intake leaks cause Hard starting & possibly worse....
I'd suggest you fix the intake leaks (first)
(stock o-rings work fine)
Then pressure test for leaks.
This link of Cotten's will explain how to...

Other wise you will never get it dialed in.
If you don't have a Intake psi tester, here's a nice set-up, that is reasonably priced, w/regulator.
This tool is one everyone should have. http://www.geocities.com/mbskeam/index3.html" onclick="window.open(this.href);return false;

After you have fixed & psi tested you will find it easy to jet right.

Panecea,

I use an S&S intake manifold and then installed a press on adapter on my CV carb. I got the adapter on eBay. They are easy to find.
There is a photo of the adapter here: http://groups.msn.com/craigpanheadchopp ... hotoID=303" onclick="window.open(this.href);return false;

To support the carb, I use a piece of 3/16" thick flat chrome stock. I attach one end to the backside of the air cleaner backing plate. Bend it about 45 degrees and bring it down to the motor case bolt between the cylinders and attache the other end there. Works really well.
You can see the support bracket in this photo: http://groups.msn.com/craigpanheadchopp ... hotoID=230" onclick="window.open(this.href);return false;

panacea-

Those ebay cv adapters are for 2 bolt intakes only.
Yes, it is (lightly)-pressed on, but before pressing, a 2 part epoxy is used, just for added insurance.
This works great!! ;D

You could have one 'custom made' for 4 bolt intake.
Or.....

Billy, I have a 2 bolt S&S manifold. I still have a cv I took off my bagger thats like new. I'm thinking that would work nicely on my 84" pan if I can locate an addapter..MW

MW-

Well then, life just got much easier !!!
I'm sure it will work nicely on your 84" Pan.
I fab similar support brackets to Craig's pic.
easy to make, just be sure the bracket you fab does not pull or push the intake, when secured.
(Craig, nice close-up !!Sharp scoot , by the way)
Just need to make it solid!!
& make sure you have no intake manifold leaks.
You can get creative w/the enrichener knob location.
I fab a baby-bracket to bolt to the backing plate, enrich/knob is right there. Mostly hidden..
(easy breezy) ;D

Thanks Craig and and Billy,I put a picture in the gallery, it's the yellow 51fl. I think a round HD air cleaner cover would be a better look than the teardrop, plus the CV would be a better carb. I dont know why but the S&S seems to run rich, but when I reduce the jet size she coughs through the carb. Possibly due to the drag pipes, which are going bye -bye.MW

That's a good question. I haven't tried using a CV with the old solid cable internal throttle. As long as it's a pull type throttle it might work just fine. The CV does have a pretty good spring for return. I'd have to mock it up to be able to give a definite answer to your questions.
Maybe someone here has used a CV with a solid cable internal pull throttle and can chime in.

I use a Legends internal throttle with a universal cable fitted to my CV, there is plenty of spring pressure to pull the throttle shut on mine.

chucklbones-

Yes it can be done. You need a reverse (pull) spiral,
& you will have to drill out a small bolt, for control wire to go thru (at carb) & nut it tight..(simple)
But after re-reading U asked about a universal cable.
Yes same, reverse (pull) spiral needed, & I solder the first 1.5" (min) of cable at the spiral, Just what sticks out of the cable housing. Just to keep it solid, & not kink, w/Emergency roll off. Just added Insurance.
I'm fussy that way.
CV has strong enough R spring to about catch a mouse.. ;D
(Safety Note) HD recommends using 2 cables...
Public Service Announcement.......
I'll sleep better now ;D Cool ;D
