CV carb on my 1953 pan

#1

Post by bibs » Wed Jan 25, 2006 6:46 am

I sent out a C.V. carb to RON TROCK for him to do his majic on.I,m puttin 'er on just as soon as I get 'er back to see if old Ron,s correct in tellin me that it will out perform my current S&S shorty.....it makes sense though,butterfly type carbs dont run as effecient as C.V. for obvious reasons....they simply shoot gas into the heads and we sit back hoping for the best and do our dammdest to adjust 'em!!!
The C.V. only allows the gas/air in according to what the motor wants!!!
I,m curious................................has anyone here tried this on their pan?

I have a CV40 on my pan. LOVE the way it works. Super easy starting and great performance no matter where I am (the altitude can change quickly in some parts of Arizona).
I have a page that talks about jetting the CV40 panheads on my web site. http://groups.msn.com/craigpanheadchopperpictures" onclick="window.open(this.href);return false;
Look for the link to the page over on the left column.

had a cv carb on my pan worked a lot better than what was on previously, you will not be disappointed
have since replaced it with a 40mm Mikuni, this works even better

waiteitei-

Not sure what size motor & mods you got, & (no offense) but, perhaps you just didn't have the CV totally dialed in ???
I would put a (properly tweaked CV) up against a Miki-flat-slide...on the dyno...No problem.
CV's will & do out perform S&S E on the dyno in both torque & HP. (w/my mods)
I use them on about everything, even have one on my Flathead/-stroker
The miki's $$$ too pricey, for me.. (I'm cheap)

I picked up another CV on eBay for $50 yesterday. Everyone was bidding up the "bigtwin CV" carbs and ignoring this one because it was from a Sportster. With the exception of jets and needle (which need to be changed anyway) the Sporty CV is identical to the others. Love the economics of the CV.

waiteitei.....
is this a round slide? or ?
I wish miki would make a flatslide 38MM, just a smaller version of the 42MM. got a 42 on the twinkie and it works great

caschnd1-

Always a nice thing, snagging one for low-do!!!
Pretty hard to beat the good gas mileage as well...
I really enjoy when owners want theirs replaced, for a more $$$ type & don't want the take-off......
Always doubles my pleasure!!! ;D ;D

Billy,

Used to be easy to get the CVs for $50 on ebay. Now they are going for closer to $70-$80 typically. People are starting to catch on. H-D dealer here used to have CVs layin' around all over the place. If you had a good relationship with someone in service they'd get you one for free. Now they've smartend up and sell em' (probably on ebay). As you pointed out, still plenty of people leaving them behind after "upgrading".

motor is 80" twin plugged and andrews a grind cam
mikuni was second hand at swap meet £10
difference is like night and day
main reason for the change was I did not like the plastic top on the CV

HOLY COW! Somebody paid $132.50 for a 1997 CV40 on eBay yesterday. This is getting ridiculous. Maybe we should stop singing the praises of the CV40.
Yeah... the CV40 blows. Terrible carb. If you have one, dump it now $25 is a fair price. You don't want that thing. LOL ;D

I have a CV on my 48 panhead built to 80 ci, kicks and runs great, a little hard to start on the cold days, but retarding the distributor helps. I just have a problem in that it runs a little rich at idle and need to re-jet. I highly recommend the setup, and the price of $35 for the CV on e-bay didn't hurt!
By the way, if anyone has jet recommendations to for this setup, drop me a line. I should add that I live at 7000' altitude! Keep the shiny side up.

Look back at reply #2. I put a link there to my website. There is a page there that talks about CV jetting (look at the left column of links) for panheads. At 7000' you might need to lean it up a little from what I've got mine set too.
