Long Boy Fuel Screw Kit

pn: fuel screw set,VL1500

$34.95 / set of 2

"Long Boy"
 VL1500 Fuel Screws

Frustrated with trying to find an "almost 90 degree"  screwdriver to fine adjust your fuel screws for best idle and cruise?
Use Factory Pro's new "finger adjustable" fuel screws to adjust fuel screws for best throttle response. Traveling to high altitude? It's easy to lean out the lowend temporarily.

Make your life easier.

Installation:
Remove old short stock fuel screws, old orings, old washers and old spring. The o-ring might be stuck in the carb, so, take a light and make sure it's really out if it didn't come out with the screw (or you can't find it after you took out the screw)
Use a small bent wire to pull it out if it doesn't drop out. Keep the old parts for "spares".

1 VL1500 Kit comes with:
2 Long Boy fuel screws
2 new orings
2 new washers
2 new springs

Bad.... really bad.....

Carb Rebuild Feedback

Also - needle jets wear out.- How to diagnose and repair...

1. I used to get 40+ mpg and now, I get 25 mpg.........

   1. If that's true for you, you will need to rebuild the carb needle jets - It's not necessary to replace the carb bodies for $800 a set.
       

   2. We will rebuild your carbs' needle jet orifices by replacing the original worn-out needle jets (they aren't normally replaceable) with our new plated and patented HDJ (High Dispersal Jet) system.
       

   3. This Factory Pro developed and patented system will both replace the worn needle jets and improve and upgrade Mikuni's traditional method of delivering fuel through the needle / needle jet area.
       

2. How special is the patented HDJ fuel delivery system?

   1. It's patented, and it IS different - if you didn't know what you were looking for in the carb - you'd never see it.
      But you'd feel the difference.
      
       

3. Benefits include:

   1. Better mileage (commonly up to 39+ if the fuel level is adjusted for best mileage, even without the airbox)

   2. Smoother running at cruise

   3. Better "snap" throttle response

   4. Better fuel atomization = reduced emissions = more power

   5. Better throttle response = fuel is atomized better = more power

   6. Better, more consistent idle

   7. Plated needle jet = lasts longer

   8. Patented HDJ fuel delivery system - not cheap round inserts w/o HDJ.
      
       

4. The carbs must be sent to Factory Pro in San Rafael, CA.

   1. Typical turnaround time is ~5-7 working days.

   2. Cost: $280 + shipping (as of 01/1/09) including:

      1.  new HDJ needle jets AND

      2. new CRB-S77-3.0  or 1.0 carb Recal Kit installed to base settings.

      3. Special!  Now includes 2 Long Boy Fuel Screws
         
          

5. AND - if the original owner ever wears out the HDJ needle jets again?  We will replace them again for $100 + S&H.

   1. Call 415 491 5920 before sending.   Thanks - Marc

That's the air filter  AND the carb recalibration kit.

Why spend $250 for a copy of the first Config 30 kit for the VL1500?

Removes the airbox
 for maximum power and the same or better lowend and midrange.

Aluminum needles

Removes the airbox. adds 3-4 True HP!
includes Filter and Carb Recal Kit.

This kit was designed within a couple of months of the release of the 1500 Intruder. Sigh - so we were the first...
It's simple - remove the airbox and install the supplied BMC or K&N air filter. Either filter flows virtually the same - so there's no drama there.
The kit was then duplicated in concept by "T. Products" and Barons.
The difference from our kit is that our kit was developed on the 4 Gas EC997 Low Inertia Eddy Current dyno - and not a dynojet dyno.
What that means to you is that, as commonly happens,  the Factory Pro kit contains the properly sized jets required to tune your VL1500. The needle profile is a lot different, also, without the problems of too rich running at low speed like some other kits.
Also, the jets that we supply are either genuine Mikuni or exact duplicates of Mikuni sizes (that WE make)  - so, if you need to use a main jet that isn't supplied, you can either order larger or smaller jets from us - or simply visit your local dealer or tuner and get some more Genuine Mikuni jets - and you are on your way. No hassle waiting for oddly calibrated dj main jets or unmarked ones either.

Biggest HP increase for the least amount of money. Runs well at low rpm and part throttle.
Uses individual K&N or BMC air filter, for general exhaust applications, stock and aftermarket, inc. Cobra, VHR, TBR, Samson, Muzzy, YRD, etc...

Suggest adding the above Long Boy Fuel Screw Set for easier fuel screw tuning.

FOR STOCK AIRBOX BIKES

General exhaust applications, stock and aftermarket, inc. Cobra, VHR, TBR, Samson, Muzzy, YRD, etc...

Aluminum needles

adds power and snap to throttle response.  Improves and smoothes power delivery at all rpms.
The best kits for Cobra, Samson, Porker, etc...

~+3.1 hp or ~6% increase w/  exh. and carb kit.
Warms up quicker.
No backfiring when pilot circuit tuned properly
