Home » KDXposed—About Us

Can you believe that this man can make any generation KDX go faster than anyone else in the World? Well it's true and has been proven every year since the first KDX 200 was introduced in 1983. From the time he threw his leg over his first KDX Jeff has produced a list of off-road racing accomplishments that is without compare.

Becoming the World's most recognized and accomplished KDXpert was no simple task. It meant loyalty, commitment and dedication to transform this undersized trail bike into a competitive off-road race machine. Because of this ongoing love affair Jeff has decided that he should share his knowledge and experience with all his fellow KDX riders. So whether you're competing with Jeff at the races or simply against your buddies on the local trails, frpoffroad.com is the place to go for all your KDX performance parts, services and tips.

Frpoffroad.com has lots to offer each and every KDX rider. Our CATALOG is full of products that have helped keep Jeff and his many customers at the front of the pack. We also keep a large selection of OEM and USED parts for your KDX. Simply tell us what it is you need and we'll reply within 24 hours with the price and availability. And if you want your KDX to be the very best it can be we offer both ENGINE and SUSPENSION shop services. These can be viewed and purchased from within the respective tip page shown above.

Long live the KDX!!!

Engine Tips

There are a number of engine performance products and services available for all KDX models which I have tried and would recommend. Because everyone operates on a different performance need and budget I have decided to list my recommendations in the most logical and economical sequence:

1989-1994 "E" Models: The first modification I would recommend is to replace the stock exhaust pipe and silencer with an FMF pipe and a POWERCORE II or TURBINECORE II Silencer. While both silencers will perform comparably, the POWERCORE II model is designed for closed courses and the TURBINECORE II "spark arrestor" model is required at all government regulated riding areas. At the same time I would recommend replacing the stock jetting with a 45-48 PILOT JET, a 152-158MAIN JET and an 1173 NEEDLE set in the middle position with the air screw adjusted out .5-1 turns. These simple and fairly inexpensive modifications will noticeably improve the performance of your KDX throughout the power band.

If you still want more power from your KDX I would recommend that you SEND us your cylinder so we can work our magic on its ports. This modification will provide even greater performance throughout the power band with more revs on top. After making this modification I would recommend replacing the stock jetting with a 45-48 PILOT JET, a 152-158MAIN JET and an 1173 NEEDLE set in the middle position with the air screw adjusted out 5-1 turns.

Still want more low-end throttle response and performance throughout the power band? Then I recommend replacing the stock reed valve with a BOYESEN RAD VALVE. If it's more bottom end performance you want I would recommend installing an FRP TORQUE RING. This small device will boost bottom end performance at the expense of only a couple hundred rpm's from the top. No additional jetting changes are required with either of these modifications.

1995-2006 "H" Models: The first modification I would recommend is to replace the stock exhaust pipe and silencer with an FMF Pipe and Silencer. There are two pipes available. I recommend the Gnarly "REV" PIPE for the more experienced rider and all other riders riding in fast terrain with good traction. This pipe will improve performance throughout the power band with the most noticeable hit in the mid-range and up. I recommend the GNARLY "TORQUE" PIPE for the less experienced rider and more technical terrain because it also improves performance throughout the power band but with a more manageable power delivery. The torque pipe is not recommended for the 220’s. There are also two silencers available. While both silencers will perform comparably, the POWERCORE II model is designed for closed courses while the TURBINECORE II "spark arrestor" model is required at all government regulated riding areas No jetting changes are required with this modification. These simple and fairly inexpensive modifications will noticeably improve the performance of your KDX throughout the power band.

If you still want more power from your KDX I would recommend that you SEND us your cylinder so we can work our magic on its ports. This modification will provide even greater performance throughout the power band with more revs at the top. After making this modification you may need to replace the stock jetting with a 45-48 PILOT JET and a 155-160 MAIN JET. For 220 Models Only: You can improve low end throttle response and add even more top end performance to this model by letting us work a little extra magic on your cylinder head and carburetor. Just SEND us these components with your cylinder and we will turn your 220 into a machine that even your 250 buddies will admire!

Suspension Tips

Suspension is one of the more difficult components to recommend to others because of the many variables that exist. Therefore I would ask that you please keep in mind that the following recommendations should be used as a guide line only and that individual rider ability and type of terrain could move you up or down a spring rate if your weight is on the border of any of the specified weight ranges.

Forks

1989-1992 "E" Models: I have found that the stock forks work pretty well for most riders that weigh less than 140lbs. I recommend replacing the stock springs with a .33kg SPRING for riders that weigh between 140-170lbs, a .35kg SPRING for riders weighing between 170-210lbs and a .38kg SPRING for riders weighing over 210lbs. For each of these weight categories I recommend setting the clickers between 6-12 clicks out.

1993-1994 "E" Models: I recommend replacing the stock springs with a .38kg SPRING for all riders weighing 150-200lbs. .40kg SPRING for all riders weighing 200lbs and up. Clickers for all weights should be set between 6-10 clicks out.

1995-2006 "H" Models: I have found that the stock forks work fairly well for most riders that weigh less than 140lbs. I recommend replacing the stock springs with a .38kg SPRING for riders that weigh between 140-190lbs and .40kg SPRING for riders that weighing 190-220lbs. .42kg SPRING for riders weighing 200-250lbs. For riders over 250lbs or are not sure of the spring that is right for you please CONTACT US. For each of these weight categories I recommend setting the clickers between 8-14 clicks out.

By following these recommendations I am confident that you will notice significantly improved performance from your forks. For 1993-2002 models only: You can improve the performance of your forks even more by SENDING us your forks so we can replace the stock valves with Race Tech GOLD VALVES.

Shocks

1989-1994 "E" Models: The stock spring seems to work well for riders between 150-200lbs. For riders weighing over 200lbs I would recommend replacing the stock spring with a 4.8kg SPRING and set the sag at 3.75-4". The type of terrain you are riding will determine the correct compression and rebound settings. I recommend setting the compression adjuster (located at the top of shock) at about 6 clicks out for faster terrain and 12 clicks out for the slower more technical terrain. The rebound adjuster (located at the bottom of the shock) should be set from 8 clicks out for faster terrain up to 14 clicks for the more technical stuff.

1995-2006 "H" Models: The stock spring seems to work well for riders that weigh between 180-210lbs. I recommend replacing the stock spring with a 4.6kg SPRING for riders weighing less than 150lbs, a 4.8kg SPRING for riders weighing between 150-180lbs and a 5.2kg SPRING for riders weighing 210-240lbs. 5.4kg SPRING for rider more than 240lbs. The type of terrain you are riding will determine the correct compression and rebound settings. I recommend setting both the compression adjuster (located at the top of the shock) and the rebound adjuster (located at the bottom of the shock) at about 8 clicks out for faster terrain. For slower more technical terrain I recommend setting both the compression and rebound settings at about 12 clicks out.
