Now with the new, even cleaner running, patented
Gen 2HDJ
Hi Dispersement Emulsion Tube!

This yzf450 carb recal kit was designed with as much care and attention to detail as we give to our EC997 dynamometer and test routines, our Shift STAR shift improvement kits, our Billet Engine Covers and all of the other products that the quickest road racers in the USA and World used to collect a total of 9 WERA and F-USA national Championships - along with the Suzuki Cup World Champion, Rob Jensen.

    We've now entered the off-road arena to bring some new, exciting, well proven concepts, such as our easily tuneable "HDJ" style jet kits and several other things that we've picked up along the way.

    One of the improvements was dyne systems design and test routine design - We have been saying for years that inertia dynos were misleading and now, these new "HDJ" carb kits show how much better the EC997 load dynos are than inertia dynos when it comes to developing any performance products. Sounds a bit egotistical? Perhaps it sounds that way - but, I think that we've got quite a few local Norcal racers that we've done FCR fine tuning work for that would agree with us.

We really aren't egotists -  We are just passionate about fine tuning.

Figure better hot starts, better throttle response, less bogging and the Factory Pro bonus - 4% to 7% power improvement, pretty much everywhere

   The Factory Pro HDJ kits, designed by Marc Salvisberg, will run more evenly over a wider temperature and altitude range than any other carb kit and will produce 3% to 8% better power than another carb with the "best main jet" in it, when properly tuned and tested under a real load. This does not mean an inertia dyno - though, power will be better with a dealership level dyno, also.

So - Here's the power - Buy it!   Thanks!    800 869-0497

EVO Shift STAR kit

We all know that the easier the bike's systems work, the faster the rider is,  less tiring it is and the more fun it is to ride.

Marc Salvisberg of Factory Pro has been "blueprinting" transmissions for years - learning the ins and outs of shimming, alignment, clearancing, gear engagement and shift mechanisms. He's been one of the sources of information for why many of the newer bikes shifting better than the "old days".

Some factory roadrace teams bought our kits and then supplied that information back to the OEMs - and - in a year or two, shift mechanisms were better on the new bikes.

Factory Pro has painstakingly and meticulously developed a new off road Shift STAR along with a new competition detent spring and microbearinged Detent arm kit that will make both up shifting an downshifting much more precise and effortless - and virtually eliminate missed shifts.

You'll think that you have a new bike.

Sound like what you want??
Ubet! :-)

Awesome Billet Clutch Cover!!!! Like our CRF, DR and KLX Covers - Virtually Indestructible!

Designed and manufactured by the same people who make the toughest roadracing engine covers in the world - Factory Pro engine covers stay together and laugh off 140mph lowsides!!

Machined from a solid block of incredibly strong, fine grain, extruded aluminum alloy in northern California on the latest in high performance CNC machining centers.

Offroad and comp tested every weekend (and sometimes during the week!) - crashed by the best of us and still looks like a million bucks.

Make your friends slow down to check out your SWEET "billet" cover!

Unlike the stock, cast aluminum cover - the Factory Pro cover, almost 99% of the time, prevents the brake pedal from punching a hole - You'll make it home!!

A lightweight 368g - or.... less than a "1/2 quart of oil" heavier than the brittle, stock clutch cover.
In other words, the cover weighs less than that quart of oil that the broken stock cover left on the trail.....

and it looks bitchin'!

First step is to eliminate the fixed main air jet restriction.
It's about 40mm down the MAJ hole (left picture).

Set your 3mm drill so that it has 45mm to 46mm of drill bit exposed from your drill chuck.
(see right picture)

Remove the stock emulsion tube (that's what the main jet screws into) so that you can clean out the carb well. By only having 45mm to 46mm of the drill bit exposed, it prevents you from drilling too far.

Then, use the supplied tap from our HDJ carb kit, thread the Main Air Jet (aka "MAJ") hole.
You only need to go far enough to be able to thread in the new replaceable jet that we supply.

Clean the hole, of course.

After it's clean, complete the MAJ Modification by installing the supplied Main Air Jet and installing the new Factory Pro HDJ Emulsion Tube.

NOTE!!!
If you aren't confident in your ability or in your understanding of what you are trying to accomplish - no worry - Call us up or talk to someone locally who has more experience in these matters.
If you are still not sure, see if there's a Factory Pro Tuning Center locally or visit your favorite local dealership or shop and get some help there -

We all have to learn, and usually having an experienced person around makes everything "easy".

This modification is something similar to what we've done in many different carb types over the years, though it might be new to some who haven't used our "1.7-RK" carb kits before.
