Ouch - those little buggers take a long time to heal. Scaphoid fractures are common in motocross. There's poor blood flow to those little bones in the wrist and sometimes it takes years to recover from a simple little break.

took me nearly 10 weeks to heal important lesson learned.

i can see i dont have that kind of compression!

As i keep finding really weird repairs i dread pulling the engine apart without having a full rebuild kit on hand..
