On my dads 03 xr400r a couple of times he has fallen off (nothing too big) and when we pick up the bike and inspect it to make sure there is no damage we notice that the forks are twisted because the front wheel doesn't line up straight with the rest of the bike. When we notice this we undo the bottom triple clamp bolts loosen them off and straighten the forks. We believe that the triple clamp bolts need to go a bit tighter but we are afraid of stripping the threads out. We have two xr400r manuals and neither of them state a torque specification for these bolts. Dads bike is in great condition with only 6500km on it and has been maintained well. any idea on why the forks are twisting and how to stop it doing that. Also a torque spec for the triple clamp bolts bottom and top would be greatly appreciated thank you.
