i think we may have missed the obvious
reads like the triple clamps are twisted out of alignment. easy to do on the skinny forks on an XR. i have twisted them in races, just landing into rutted corners with breaking bumps, didn’t even have to crash.
it’s not that anything is bent, just missaligned. the forks have twisted in their clamps
i just sit on the bike and swing the front wheel so that it bangs into a tree/post. have a look now to see if the front guard is square with the hangers. if not do it again until it is. if it goes to far: bang it the other way. then ride the bike and see how it feels.
this can all be done without getting of the bike. then catch back up to your mates.
if you really want to make sure they are aligned in the shed. elevate the bike so the front end is off the floor, loosen the top triple clamp (even the headstock) wedge a srewdriver in the gaps of the fork clamps and give the handle bars a wiggle to let them settle straight
