[dehner47]

i have a walsh chassis with a 426 motor in it. i'm in need of the motor mount bolt that runs threw the front of the motor and threw the 2 motor mounts. is that bolt a stock yz426 motor mount bolt that i can get at my local yamaha dealer or is it some kind of special bolt. if someone can please help me with this so i can get this pig back out on the track. thanks everyone in advance

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 dont think hes talking about the swingarm bolt but the front motor mounts bolt that goes through the cases

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.
