Ouch! What's that from? What happened?

My son’s ‘94 XR650L. Apparently he let the oil get too low. Lost compression, as you might imagine.
It appears the bore is not fatally damaged (steel sleeve). Going to try stuffing another stock size piston kit in there.
It’s a learning experience: Watch your oil level!
I am about to do a tbs on my 2019 A and cannot find paint on any of the screws. I think #3 cylinder is the reference but theres no paint on it. I just deleted the pairs. Can Anyone verify which screw is the reference? I bought the bike recently.
Been here since 07, first time I read it that way, but I do skip things some times!One of the screws will be full CW, lightly seated. That’s the one with lowest vacuum when they are all fully CW. Then they open the other three up to match that one. This way you have the least amount of bypass air going through the balance screws, and the most going though the throttle plates under Idle Control Valve regulation.

Wait! A son of yours let the oil get too low grenading the motor???? I am not buying it. Doe he have any resemblance to the postman?
Although it's expensive, I'd go with Yamaha Ring Free. A forum member (Dave / Wynpro?) used to make the plates. IIRC he stopped making his accessories a few years ago. Maybe search eBay?Are you recommending Yamaha Ring Free, or one of the many more reasonably priced alternatives? I’m still not convinced rings are the issue. I did use Motul Engine Clean the previous two oil changes. And since I am asking questions, is there a PAIR close off kit you recommend?

No special kit needed. You can get everything at an auto parts store. This video explains how.Are you recommending Yamaha Ring Free, or one of the many more reasonably priced alternatives?
