I'm parting out a YFZ450 and I think I have what your talking about. I have a box of bolts and I think I remember that one. I'll let you know later tonight

not sure on the walsh frame but i do know if you use a honda swing arm the yamaha bolt wont work. the yamaha bolt is bigger than the bearings in the swing arm. on our ex conversion we had to have a special sleeve made that went in the motor and made that hole the same size as what is in the swing arm.

I`ve in the past reamed the hole out to the next size larger, a 7/16 .0437

Then gone to the hardware store and got the correct leangth bolt.
