So here’s a problem we can’t figure out. Our bandit 600 is getting no oil on the left side of the valve train. Right side is fine. We’ve checked the galleries and lines with compressed air and nothing is blocked. We can’t figure out why this is going on. It’s a long shot but I couldn’t find anything on Google so I figured I’d ask the audience.

As I was writing this we found that the left side galleries do pass air, but are more restricted than the right. Posting this anyway in case that isn’t the problem.

Unfortunate cam lobe for your time.

EDIT whatever we did, when we put it back together the noise stopped.
