My mate rick was having Drama’s on my WR450 every time he went over an erosion mound the suspension wanted to speer him off into the bush:silly: We thought it may of been a build up of air pressure but it was worse than that. RiderX suggested to check the alignment of the forks,:dry: yeah Ok never heard of that before :dry: but we did it to his directions and Voila!! worked like a charm;) Thanks X. I plagerised this from another forum but is basicly how X described how its done.This should be done evey time your front wheel is removed.

Fork alignment
Check your R/S fork for binding like this………….
One of the most common fork problems I see is bound up forks due to improper installation of the front wheel. Its very easy to avoid this problem by taking these easy steps…
1.) Install both forks and set fork height using calipers or a ruler. It is important that fork height be exactly the same for both sides. Tighten pinch bolts to the proper specs (Top: 18 Ft-Lbs | Lower: 15 Ft-Lbs).
2.) Install the axle and tighten the axle nut to proper spec (75 Ft-Lbs). If the axle turns while tightening, tighten one right side axle pinch bolt to hold axle in place.
3.) Tighten both left side axle pinch bolts to spec (17 Ft-Lbs).
4.) With the left side axle pinch bolts and axle nut tightened, loosen the right side axle pinch bolts. Take a small flathead screwdriver and carefully tap it into the slot between the two right side axle pinch bolts. This will enlarge the axle hole. You will then be able to grab the bottom of the right side fork tube and push it in and pull it out freely. The fork will settle naturally into position on the axle without binding.
5.) Remove the screwdriver and tighten the right side axle pinch bolts to spec (17 Ft-Lbs).
If you’re wondering if your forks are currently bound up, put your bike on a stand and start this procedure at Step 4.
Bound forks are a leading cause of premature bushing wear, air build-up, and fork harshness. All of which can be avoided by following these easy steps.
