81 YZ 465 first ride
This is the very first ride after resto, nothing impressive, just working the bugs out. Still needs some work, clutch arm popped out of the case, it is worn in the retaining slot area. Jetting may be off, not going to bother with it until the "break-in gas" is gone. Running 30:1 right now and seems a bit lean, but might be fine once I run a normal 40:1 ratio. Hopefully the next video is a real ride, before snow hits the ground.
