    Are there different versions of the "Velocity" needle? I orderd one for a 88TC dyna - wondered if it will work in a 883 Sporty? Or is there a different version for the sporty.

    While I'm asking.....any recommendations for jetting (incl needle) for a 2004 883 with stock pipes/modified baffles and high flow air cleaner? Thanks!!!

    The only needle that is different for a Sportster is for the 2004-2006 XL 1200 that had the XB heads. The needle you have will work for your application.

    Jetting - on a Harley 883 with a high flow air cleaner I recommend a #44 pilot jet and adjust the mixture screw (or EZ-Just if you have that).

    I recently purchased the CVP Velocity Needle and the CVP C65. I was wondering if anyone knows the specs of these two needles. I tried contacting CVP via the website but have not heard back from anyone. So if anyone can help out with the tech specs for these needles so I can decide which needle might be better, it would be greatly appreciated!

    Thanks

    Hi Waikryder, the N65 needle we make is identical to the factory N65C needle originally used on 1988 Sportster to overcome an off-idle hesitation. Tuners have been using this needle exclusively for the past 24 years for a richer midrange. The N65 needle has a broad range from 1/4 throttle up to around 2/3 throttle. Many tuners use shims with this needle when seeking a richer mixture just off idle.

    The Velocity needle is our own design and uses 3 steps and tapered sections that gradually ramp up between each step. The design allows for very good off-idle reaction without becoming overly rich at half throttle. Our needle also eliminates the need to shim or adjust.

    Hope that helps.

    If I'm getting hesitation/popping and loss of power in the mid range which needle and setup would you recommend?
