You'll get to see this one soon Ashman. The primary chain guard is at the welders right now getting covers on the clutch and alternator. The it's done.

I bought the rolling chassis in 1984 and was given most of the engine by a friend. I made the engine mounting plates myself and had always assumed it was a 750 Commando. Only recently did I check the engine number to find it's a '64 Atlas. I knew the engine came from a rigidly mounted frame in a drag race bike, so I just ran it and never checked the crank balance. It's nice and smooth. It supposedly has all the wrong parts in the oil system: low pressure pump, scrolled rocker arms, vent holes in the conrods, but it's been raced for decades and never had a major failure. My only worry is that maybe the fact that on the race track it's screaming it's nuts off so always has good oil pressure. Now I'm going to use it on the road maybe it will be a problem if I'm just cruising along?
