Heres a link you might find interesting-
43 USD vs 48USD vs Extremes- rider opinions
And, as velo says if you have a 3 bush USD its easy to remove or reverse 3rd bush and drill the bleed holes in fork legs. Makes a huge improvement.

There is a SXS-kit which will improve the performance.
Some of the WP-bushings don't work very well.

===== <u>Simple things you can do for better performance</u> =====
Some ideas that should always work:
1. Polish up the cartridge rod, springs and the inside of the cartridge.
2. Machine polish the lower leg for better finish-careful!
3. Purchase Race-Tech Gold Valves or similar (see below left). The 'Nost SS' basevalve (see below right) is like a re-valve with just the turn of a screwdriver. There is a bottom valve that you adjust 4-ways externally high speed, mid speed, low speed and supplenes (Viking).

4. Update internals (see above) especially machining the rebound taps.
5. Terry Hay's top out springs said to help the racer (70mm long).
6. Drill a 2 x 5mm holes (direction: across the bike) 18cm up the inner leg to halt air bilging.

7. Drill 2 x 2mm holes in the bottoming cones. One down 20mm the other down 40mm and around 180d apart.
8. Try fitting some oilly sponge under the dust seals.
9. Get the suspension right and THEN fit 'sub tanks'.

Hi Taffy
I am trying to get a better picture on above statment #6 and #7, drilling the hole part and locations. No rush, when you get a chance draw a picture or more detail description of the exact holes location on fork.
Thanks.

Drill 2 x 5mm holes Parallel to axle line, 170 mm down from fork leg top.
Deburr internally with 1/8" shank ball end stone in dremel tool.
Thank Terry for this mod- makes a huge difference coupled with 3rd bush reversal/removal if your fork has them
My 04 300 EXC is a world better for it.

it made my forks plusher (as i've reported). i did it as well as two other small jobs. i had the taps machined and the cartridge rod polished.
all i know is that it did it in a back-to-back test.
maddel will put a photo of the bottoming cone drilling mod in the doc in the next day or so so keep an eye out.
