KILLER MOTORCYCLE Harley Carburetor Rebuild.

I have a 1999 Harley Davidson Fatboy with a CV40 Carburetor and the Cool Evo Motor. I have been fighting the carb for the past 3-4 years. The bike has 58,000 miles on it so it has ran a lot of gas through it. I have had the carburetor off my self and cleaned it. Checked the Timing on the Bike, changed the Plugs, wires, jets, etc. Well the bike kept getting harder and harder to start. When the bike was cold I would really need to crank it over to ever get it to fire. Only after Popping and back firing into the Carburetor a few times would it start. All indications were that the Carburetor needed fixed but I couldn't get it right.

I found Killer Motorcycle Products, on ebay and took a chance and sent him my carb. Then I went of to Sturgis and didn't worry about it. When I got back my shinny new Carburetor was on the front door step ready for install. I did get my exact same Carburetor back I just calling it new as it was polished and looked brand new. I spent a couple hours and got the Carburetor put back on.

This was the moment of truth. Would my frustration with this bike end or continue? I hit the starter knowing the Carburetor had no gas in it and the engine needed to open the vent so the carb could fill before it would start. I let it turn over about 10 times and cranked the throttled. Bang it fired right up. Cool. I turned it off and waited for morning to give it a test drive. The neighbors have a thing about midnight Harley noise making, I just don't get it.

Well yesterday I rode the bike to work and for an extended Lunch run. It starts right up, burns a lot more gas, and doesn't pop at all out the Carburetor or tail pipe. I am very happy with the results and now have my good old reliable FatBoy back. It is a lot richer at idle especially with the choke on. This bike was always lean maybe that what lead to my troubles.

I can say that I was worried sending my Carburetor off, not knowing what to expect, but the results were very good. I am not sure of the price, it did seem kinda high but now it work no worries. Thanks Dale.

Do you have another contact for them than ebay? I dislike paypal and ebay with passion.

Please email me from my blogspot email if you can help.

I am excited to find them as I too have been wrestling the 40mm carburetor conundrum. H-D dealership says the item is discontinued could not even find me a slide/diaphragm in parts book. I said, "you have to be kidding, Harley used that same carb on all their bikes for over twenty years". I do have a new diaphragm/slide coming in the mail from another H-D dealer, but I want a pro rebuild.

Hate ebay and paypal, hate em! Any lead to Killer would be most appreciated!!

I will make it easy here is my blogspot email address:

You've got to be kidding. I read that ad on EBAy last week and thought it was a hoot! For all the change in performance, you'd do better by attaching baseball cards to your spokes. Read How to Build a Harley Torque Monster by Bill Rook for a great article on modifying CV carbs. It's a nice carb, but spending that kind of $$$ for glass beading a carb throat and getting a little plate that says "Killer" is crazy. I installed the YOST CV40 kit which is fine, though I think you could get the same effect with a much cheaper rejet kit.

I was have problems with starting and power under throttle on my 91 Heritage. I've had it apart many times since new. 2 sets of pistons, countless cams, ignitions, 2 Mikuni's. kited CV's etc.
It's back to rideable with 9.5comp, CC EV-10 cam, stk Ign, & true roller rockers. It had gotten so hard to start I had given up riding. Saw this Guys ad on E-Bay and took the chance. Sent it off went on a trip to Florida and when I got back the carb was there. Put it on. Let the gas drain into it, puller the choke and waited for it NOT to start. Was I ever diappointed. It started up with in the 3 turn overs and all I've done is adjust the idle screw. The bike has unbelievable torque off idle and instead of flatening out under throttle this thing took off like a bat out of hell. Man it was like the good old days. I'd recommend this guy to anyone. I personally talked to him about how he left all the settings and how to make any adjustment if I ever do. He said he did 600 CV's last year and hears reports just like mine every day. This guy knows his s--t.
