Long Boy Fuel Screw   $23.95

pn: CRZ-SCR-4010-K
 with new spring, washer and o-ring

"Long Boy"
 Single carb VT600c / VTX1300 hand adjustable Fuel Screw assembly

Frustrated with trying to find an "almost 90 degree"  screwdriver with a "D" socket to fine adjust your fuel screws for best idle and cruise?
Use Factory Pro's new "finger adjustable" fuel screw to adjust idle and cruise fuel mixture 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 screw, old o-ring, old washer 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 VTX 1300 screw assembly comes with:
1 Long Boy fuel screw  CRZ-SCR-4010-K
1 new o-ring
1 new washer
1 new spring

 Dream come true! SMOOTHER shifting.

Factory Pro's famous
VTX Evo Shift STAR kit

Myth:

Big, strong cruisers have big transmission gears and they generally shift "lazily" and clunkily, unless you use "exactly the "right" rpm and throttle.

Reality:

If you ever make a quick shift and feel and hear the gears grind / ratchet before maybe engaging - that is what causes shift fork and gear damage - especially in 2nd gear.

The EVO Shift STAR  kit - It's everything that I ever wanted to do to a shift mechanism -
A new FP MicroBearing detent arm and the final piece... A completely redesigned, empirically refined, multi angled, variable radii, repeaked and valleyed FP Shift STAR.
This kit will totally change the feel of the bike as a whole. The shifting effort is about the same - but the speed at which the gears actually engage is dramatically improved - Quicker, easier, shifting - A "twitch" on the lever and the throttle and you are in the next gear. Perfect for track use and road riding for effortless downshifts into a corner and just a "tap" to upshift without any more than a "twitch" off the throttle -
Missed shifts virtually disappear.

In town? Low rpm cruise in second - shift to third? Quicker and smoother - NO more clunky, lazy shifting in town - it's different and improved.
Proven concept - Virtually all the Factory Pro Support riders in the AMA and WERA multi- Champions Vesrah Racing tested and proved the EVO-7 Stars.
 

Kit includes a new detent arm with a low friction microbearing roller and the NEW Factory Pro EVO Detent Star.

It's a "relatively  inexpensive" kit that will smooth out shifting over stock and help prevent shift fork damaging missed shifts.

I recently purchased your jet kit & Longboy screw for my 07 vtx 1300, after trying to get my setup right with the Barrons BAK jet kit for 6 weeks, with no luck. I put Factory Pro jets and needle in, and Jackpot. my first setup seemed to hit the nail right on the head. I will never fight with another companies jet kit again. From now on its only Factory Pro.

Final setting for 2007 Honda VTX 1300 - 215 Main jet  - 58 Pilot jet - clip on 4th notch of needle - A/F screw 1 3/4- 1 7/8 turns out  -100 % humidity - Average temp 95 degrees - 100 ft above sea level
Thanks for a great product Factory Pro.

 carb kit for the 03-09 VTX1300s / c / r  t.

This is the kit that is used to replace dynojet designed kits
Works great with 
Hypercharger  / Hypercharger Pro, S&S, Thunder, Baron's BAK and similar air box mod kits -
Maxair already supplies a special version of this kit bundled with their products.

This is the kit that generally adds more low-end / midrange than stock or dynojet, if the proper main jet is selected, more top-end power. Easy to install and tune - no slide drilling.
Includes pilot, needle and main jet selection for perfect tuning - and the best tech support in the industry -
800 869-0497

Tech notes:
Some VTX 1300's came with what we call a "2.9bt" clip area configuration and some didn't.
The difference is that the clip area of the needle might be 2.9mm and the hole in the slide that the needle goes into may only be 2.8mm. The immediate solution. if you have that mismatch, is to use a small drill bit to enlarge the slide hole.

Tuning:
Proper tuning involves trying a couple different main jets, till you find the set that pulls the hardest at "high" rpm and upper midrange. It's rarely under 210 with our needle.
Then, raise or lower the needle till you get the best full throttle midrange.
If you've done that, then, 99% of the time, you'll have very good cruise and throttle response.

The low speed mixture:
Adjust the idle speed for lowest possible idle.
Then, adj the fuel screw for the best/highest idle.
Then readjust the idle for lowest possible idle, again.
Then readjust the fuel screw for best/highest possible idle.
Now, you have the fuel screw exactly where it wants to be for most efficient idle.
Then, finally, raise the idle speed adjuster back up to where you want it to idle.

If necessary, trim the fuel screw for cleanest cruise.
(that will slightly un-optimize the idle, but optimize the cruise smoothness and mileage)

Note on pilot jet size:
If the fuel screw ends up at 1 turn or less, the pilot jet is probably too large. If you are more than 3.5x out, then the pilot is probably a size too small.

Notes:
The dynojet / thunder / cobra needle is excessively rich in the low rpm area, so it's not reported to work well. The Factory Pro needle is improved over the other needles, including stock. The dynojet / cobra / thunder needle is what people complain about when they say "aftermarket" needles are "finicky" (not ours).  Shimming a stock needle might still leave some low rpm flat spots. If you have "the flat spots" after shimming the stock needle, you need the Factory Pro kit -

Installation Notes:
"Needle Post"
When you take the white, plastic "needle retainer" out of the top of the slide, turn it over and you'll see a small spring, about the same size as a retractable ball point pen spring, wound onto a plastic post.
You will need to cut the "post" down to 1/2 height to give enough room for the longer Factory pro needle.

HANDY Tech tip!
If you lose your stock "needle retainer" spring, sometimes you can use a ball point pen spring as a replacement.
Use your judgment......

Holy Shite!
Sweet! Scooter running SO much nicer! Took bike to shop this morning for 27,000 mile service, MaxAir box installation, and rejet with your kit I bought (VTX1300). Absolutely night and day difference.
Thank you so much for what you've done!  Gorgeous. Chris Blake
.......................................
I just wanted to drop you all a note and say this jet kit is awesome. After losing almost a whole riding season because I couldn't get the Dynojet kit to work right I wish I would have found your website earlier!! No matter how hard I tried I could not get the pilot jet set right and always had 1/4 throttle problems.
You all really need to be sure your products get the visibility they deserve because the difference is indeed day and night.
Sincerely,  Eric Kretler

We are interested in properly tuning bikes- not "what's the least I can get away with".

Sept 2012

We had a terrible time trying to tune my 2009 VTX1300 using a set of Dynojet components after adding slip on Cobra pipes (slash cuts), and a K&N filter element. After a little Internet research, we ordered and swapped out the Dynojet kit initially installed and swapped in your stage-1 Factory Pro Jet Kit. Our first try - as your instructions recommended: set the needle with clip fourth from the top, installed the 215 main jet & 58 pilot jet, used the stock springs, clipped the plastic spring/needle holder as described (1/2 clipped off), set the fuel/air to 1.5 turns, and PERFECTION! There was no rich or lean backfiring, no dead spots at any throttle/gear settings, and there is an unmistakable power boost - especially on the high side. The bike is now very happy with easy start ups on cold mornings and smooth, powerful operation (near sea level) through the days. Gasoline mileage has not changed at all, which surprises me, given I now tend to really throttle it up to speed. Well done Factory Pro!!
