Attaboy, Pilot !!
I saw some of these on some surplus Web site, and you can imagine what I was thinkin'. Later saw some on a KTM at Mid-Ohio, but saw no trace of the owner. Been real curious about it until now.
The inner cans look about perfect for dippin' carbs, or for tool boxes instead of the ever-popular, perfectly hideous PVC pipe. In fact, they look just like something I was looking for lately, but doggone if I can remember what it was.
Very nice job on the tutorial!
AndrewH is lookin' at a pair of these...think you can whip a tape on'em and give us the dimensions?
