CV will give you the best gas mileage and are as reliable as death and taxes.

I would set yours up as follows

Low speed jet #48
Main #190
Needle stock with 1 shim

Or try the Sporty needle.

I like my Edelbrock Qwiksilver II but they're hard to find so in it's place I'd use a CV with sportster needle, 45 idle jet and 185 main on your EVO. Throttle response will be just fine, although you may lose a nanosecond or two to a Mikuni or Edelbrock flatslide. I'm no expert but one of my riding buddies is and in his opinion the expense of the Mikuni is hard to justify until you're putting out 90 HP or more. You can get there just fine with the CV.

I just finished tuning my '97 Sportster Sport with that exact combination on the otherwise stock CV. It's running an open Supertrapp header with no muffler just a straight pipe and runs like stink. Love that little bike... ;-)

your so cool

Ontario Eh ? you better get the mods done soon if you want to test everything out, we're running short on good days.

Haha! I think we have to face facts, we're out of good days completely (except for the odd clear and dry November day)

*sigh* testing will have to be done on the dyno and in the spring...

Very pleased with throttle response & milage. My 42 is setup with 17.5 pilot, 50 pumpjet & 165 main with 98 needle middle setting.

The CV carb will work, might have shim the needle a touch

That's almost exactly the way my HSR42 is set up on my bike. I DID bump the pilot jet up to a #20. This seems to help with cold starting and the occasional cough on trailing throttle. I figure it's because we're forced to use E10 around here.

I have been wrenching Harley's for a couple of days (about 1,000,000) Played with a lot of carbs , I have tuned cv carbs with great results. I would put mine up against a S&S or Makunie any day.
