CVP Velocity Needle

<p>Amazing product, even throttle response from the bottom, no flat spots whatsoever like on stock needle. I run with cvp accelerator pump nozzle and emultion tube. With single fire ignition, high flow ac and 2-1 pipe I get 62-64mpg just cruising on my 80”evo FXR which is insane. My bike rips like crazy.</p>

<p>I fitted the needle, needle jet and emulsion tube into my ‘89 XLH carb with over 100,000 miles on it. What a difference! The bike ran well anyway, but the ‘doughy’ feeling when cold has completely gone. Throttle response also better. I didn’t touch the jetting or idle speed, didn’t need to. Awesome</p>

Last summer I did a Daytona twin tech ignition system, woods cams, 2into1, and a bunch of other stuff. I never could get the carb just right so I bought this needle last year shortly before I blew my clutch hoping it would help but didn’t have high hopes. Yesterday I finally got around to fixing everything, I installed the needle and holy s*** it has made a WORLD of difference! Everything is just better and I have very very minimal decel pop now. I can’t recommend this product enough. It’s helped so much that I’m considering sticking with the CV carb and not going to a flat slide.

I got a used Keihin CV carb off ebay for my '69 XLCH 900. I messed with a few slow jets, shims under the needle and mixture screw settings. Got it to start easily (magneto), idle good, run good and get good MPG (mid 40s). But could not get rid of the occasional carb hesitation.

Read about the Velocity Needle on the XLFORUM so I gave it a try. It was the final key. Not only did the carb farts stop but I went down one pilot jet size to a 42. Starts, idles and runs great. Plugs are burning just right (Auotlite AT 42) and MPG is mid 40s around town.

I'm ordering one for my 2004 Roadster 1200.

Stock twin cam 88. This needle makes the stock one look like a tree trunk. I put this and a 48 jet in and the bike jumps when you twist the throttle at 30mph. No hesitation and no pop on decel. Twist it at 70 and it will get to 90 respectfully where before, you heard the exhaust but the speedo didn't move. To do better, you would have to change cams.
