An extract from another V-Strom site that was useful to me: "Here's a quick procedure I found for untwisting forks:
- Place bike on stand to get the weight off the front wheel.
- Loosen (slack off) fork bolts that go into both upper and lower yokes
- Loosen fork / axle pinch bolts
- Ensure both forks are exactly the same height (above or below top triple clamp).
- Align everything.
- Torque triple clamp bolts
- Torque non-threaded side axle pinch nuts
- Torque threaded side axle fastener
- Take bike off stand
- Grab front brake hard and rock bike vigorously back and forth
- While bike is upright (not on side stand), torque threaded side axle nuts."
To me, the final step from the list above is for the axle pinch bolt that clamps the built in spacer side on the front axle. The axle spacer side can be easily be clamped in the wrong position and could cause the front wheel to pull to the one side. The bouncing step allows the fork to settle in the correct alignment position on the built in axle spacer.
