A friend of mine has a Heritage and his carburetor just wasn't working right even after the dealer rebuilt it. He found a performance CV on EBay and loves that thing. I have had a lot of good luck with Mikunis in the past. Being an old time street drag racer My all time favority carb is the S&S shorty. If you are going to pay any where close to $400 bucks then go to the S&S page and read up on their shorty carbs.
