| XR Rear Wheel Adjusters - If you jump your XR a lot you
can collapse the rear wheel adjusters. To prevent this Robert suggests
welding two together. Keep in mind if you do both sides the axle
nut may not fit. By Robert |

| XR400R Baffle Mod - Remove baffle from spark arrester.
Cut ¾" thin wall pipe ~ 4" long. Weld a washer to the
end of the pipe. Make the outside of the washer fit the inside
of the spark arrestor. Drill holes in the new pipe. Buy a new longer
set screw to wedge the new baffle. This mod gives more bottom-end
snap and is less noisy than no baffle. Mod by Bruce Doenz, submitted

| XR400R Head-Pipes Mod - Remove the head-pipes and use
either a grinder, Dremel or send to a machine shop and cut back
the welds. Not too much to weaken the joint but enough to increase
flow. This will improve top-end. By Barney |

| XR400R Fork Spring Rate - The standard fork spring rate
on most XR400Rs is .39kg (~.38kg measured). You might have better
luck with heavier springs in the area of .42kg-.46kg, depending
on your weight and riding style. By 4Strokes.com |

| XR650R Radiator Guards - Richard recommends not removing
the factory radiator guards on the XR650R, as he has tried a set
of aftermarket aluminum guards and noticed no improvement and even
slight overheating at low speeds. By Richard Ranz |
|
| XR70R Shift Lever - If you break an XR70R non-folding
shift lever, an XR200R folding lever can be used. We have a '98
XR70R and a '99 XR200R. When the lever broke on the XR70, we tried
the XR200 lever and it fit perfectly! It may work on the XR100R.
