Jbird and Mich - so what else did you dial in for your edelbrock?

I am thinking of getting it and if i install it where should i start as far as tuning it. My bike is pretty similar to yours (i think). I have full FMF powerbomb/powercore4 system, K&N, desnorkeled and desmogged.

Barnums pretty good seller? 389 right now online...

It took two weeks to get mine from Barnums to Houston but everything was there. The only thing I did to mine was change the needle and adjust the idle. There is a pump adjustment but mine seems to happy with the way it came. I'm on the road right now and can't remember which needle I installed. There are no jets and you install a different needle to increase or decrease jet flow. Other than put in the the different needle, all I did was adjust the idle knob until the bike idled and came off idle with out hesitation. Most people count the number of clicks out from bottom and keep a note of it but I didn't do this. It's so painless and effortless to do, I didn't get that anal about it. The biggest problem is letting go the money to buy the thing. I should be home Friday and will let you know what needle I installed and count the number of clicks the idle is set to.

Any info on how to dial it in would be really appreciated. Jbird - what exhaust and mods do you have? if close i will start with your settings and adjust from there.

mine - desnorkeled, desmogged, full FMF powerbomb/powercore4, and K&N (soon UNI). stock engine for now.

thanks guys!

when i went pumper i ordered both the mikuni and the Edelbrock and after looking over the two carbs I decided the Edelbrock looked more rugged and better sealed then the mikuni and that was the only reason i went with it. i love it except for a sticky slide which i think a heavier spring will fix.

I've seen several posts about the slide sticking on Edelbrocks. When I installed mine, I changed the needle to the one that flows more gas because I knew I had more air flow than stock. When I put the slide back in, I put a light coat of a synthetic oil on it. The oil is some kind of special oil used to lubricate watch gears that I got from a computer company I used to work for. We used it to lubricate high use printers we serviced and maintained. I don't know if this makes a difference or not but I've never had a problem with the slide sticking on mine. It's made by a company called Nye and don't know if it is still available or where to get it.

I'm running a big gun race pipe, all the air box mods on my L. The Edelbrock needed no adjustments- ran great right outta the box, I'm at sea level..
I put the "Old style" Edelbrock on my 650R a few years ago, and yes, it did have a few quirks. The one I got from Barnums for the L is the new style..
Do it, then yer done monkeying about. :thumbsup:

Nope, no stumbles or hesitation. It came set at 15 clicks from full rich on the installed (Stock) needle. I never checked the pump screw, seems ok.
Edelbrock carbs are so simple to adjust, it's had to get used to after fiddling with all the jets on the stocker. Two items to play with- needle & pump screw. Both are Turn right for rich, left for lean. Instructions come with the carb.
As I stated before, the carb comes set up for aftermarket exhaust & airbox mods allready done.
When I ran into problems on the old carb for my 'R' I called them on the phone, they helped me right then and there! GREAT service!
Don't fret- just read my starting procedure posted earlier.

I'm pretty much at sea level; maybe as high as 12 ft. My bike is set up similar to yours with the exception of having the WB E2 exhaust instead of the FMF. Because I had opened up the air box with the K&N and removed the snorkel, as well as knowing the E2 flows better than stock, I went ahead and installed the 18E needle. I checked the idle and it's set to 15 clicks. My motor is stock with no piston, cam, or vavle mods.
You may want to give it a try without changing the needle or the settings to see how it will work. Worse case you'd have to pull the carb and change the needle which takes no time to do. And, if it works right out of the box, the time you'd spent changing the needle, you can be riding. :thumbsup:

PS - Don't forget to install the adjuster on top of the slide cover before installing the carb. Easy to get in a hurry and forget.

sounds like you may have the cables routed wrong after refitting the carb, this happened to me and gave me the same probs until i got the route right again.
