Moto520's WP Extreme Settings
Ive had allot of experiance with the wp 50 mm forks. I also weigh in the 200lbs range .
I race vet A mx at RED BUD and some pretty awsome tracks around here, also GP's and scrambles. Over the years I have found that they work best, for me anyway, with the following. First when installing seals use a bullet tool or cut the corner off a plastic grocery bag and slip it over the tube to act like a bullet tool. gotta save fron the sharp edge. Remove the seal springs and unscrew where they connect. Cut 5-8 mm off the female end and reconnect. Install them . Do the same on the wipers . This greatly reduces the weeping.
If they do leak use three wrapsmasking tape around the tube with an outward slash cut, work in into the seals rotating so the dirt rolls up along the slashed edge effectively removing the dirt that makes them leak.
.44 spring at 10 mm preload, 130 mm oil level with 10 weight in the compresiion side and 15 wt in the rebound.
I use a Torco oil as its very ressistant to foaming compared to , Maxima , spectro, silkoleen, defintely stay away from Belray. The 50's have such a large bottom out cone they can be plush initially and still offer up a great bottom out action. Flex will be better than the biggest inverted fork using a Summers fork brace. I can back my comp and rebound off and go crazy in the woods or turn um in and mx as if two different forks were on the bike.
The range of adjustability is awsome with these just by spring rates and oils weights and volume. No inverted fork will match a conventional forks action for overall performance.The 4 stroke ktm with these forks on them is just unbelievable. Straddle your 48 or 43 mm forks clamping with your legs and holding the bars with the front brake lever compressed . Move the fork lft to right and see how much they move . Try that on a 50 mm fork with and without a Brace. The brace makes the difference and now the fork is clamped in four places. The little bit of flex the fork may have at the bottom t clamp when riding isnt a noticable amount and may be of some benefit. The 50 mm forks usually dont need much in the way of stack valving for most riders.
Words of experience.
