Factory Pro - The motorcycle industry's premier billet engine cover designer - and the only USA company with a cover patent - introduces a super tough clutch cover for the DRZ400 -
Machined from solid- tougher than any similar thickness "cast" cover - the cover virtually eliminates the possibility of the brake lever punching through the cover!
In fact - if you can punch a hole in this cover for a whole year from date of purchase - I'll replace it for free!

Carb Recalibration

Long Boy Fuel Screw

pn: CRZ-SCR-4030-M

$17.95
 with new spring, washer and o-ring

"Long Boy"
 DRZ400 hand adjustable Fuel Screw assembly

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 screw, old oring, 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 DRZ 400 crew assembly comes with:
1 Long Boy fuel screws  CRZ-SCR-4030-M
1 new o-ring
1 new washer
1 new spring

              
(only one screw supplied)
 

The new Factory Pro updated DRZ400 Carb Recal kit! Including Super Moto

Specially developed to address the cv carb "bog" issues.

The kit, when properly tuned, adds more low-end / midrange and if the proper main jet is selected, more top-end power. Easy to install and tune - no slide drilling.

It's not recommended to cut additional holes in the airbox, as the main air correction circuit is affected - causing either a lean spot at 8000 rpm or a rich spike at redline. Most Factory Pro Dyno Centers have the equipment to measure the skew and can perform corrections to the main jet fuel curve to gain all the power that the additional air will supply.
Without that correction, you'll always have to "split the difference" and not have all the power you could have at 8000 or at redline.
