Re-jetting a CV Carb

[ckwizard]

A friend has a '05 fxd w/ stock carb. She bought it with a free flow air cleaner and supertraps. I do believe she needs the above needle and 46 jet. I looked in her dyna manual and I don't see where the plug/afr adjustment is. Anyone got's a picture or exploded view?
I am much better with the easy to adj SnS carbs.
Thanxs in advance.   

There is a small aluminum plug on the idle jet boss on the underside of the CV carburetor. These can be removed by drilling a pilot hole through the plug (don't drill too deep!) and then by placing a sheet metal screw in the hole, you can remove the plug to access the idle jet. Sorry, I don't have a picture.

I'm one who thinks that the stock CV it the best motorcycle carburetor ever made. I've seen all sorts of modifications to them from cutting the spring, to drilling a larger hole in the very expensive, now increasingly hard to find, slide/diaphragm unit. This is not necessary.

I know that many will change the needle to a Sportster needle and install oversized jets and that's fine as long and not too many other changes are done. It's important to remember that most of the carbs could use maybe one size larger in a mid jet but certainly not any more. The stock main jet is fine because the only time that is used is a WFO throttle settings. I seldom do that so a stock jet was fine for me. The carburetor runls on the idle and mid jets for 90% of its operation.

Good luck.

Totaly correct, anything else is a waste.

What exactly is the sportster needle, there is the needle jet and a jet needle on top of the slide. thanks 9.5

you don't need to mess with the needle jet. Just the needle.  sporty needle was used on the late 80's sportsters and is a little richer needle.  Some times it is better to just shim the stock needle but either way you will be close as far as needles go.  Bob Wood sells a KT-1 needle that is pretty good but spendy.  If you do a search you can find the part number for the sporty needle.  I can not remember it off the top of my head.

the sportster needle part# is 27094-88 as posted earlier in this thread.
