034 Super Plating Chips

[Owyhee H]

Thoughts on this? It is chipped above and below the exhaust. Is the cylinder toast? Otherwise the 034 super arctic is in great shape.

I'd look for another cylinder.

Looks like it was ran lean or straight gassed one time and they kept running it. Partially stuck rings clipped the edge of the exhaust port. It’s probably salvageable for the right guy. Not all that rare, but those cylinders are a little bit sought after

You can bevel it back with a Dremel tool and a little round grinder attachment. You just want to make sure it cannot snag a ring. Can't imagine any change in port timing would be significant.

Personally, I run a ball hone up in them a couple of seconds both ways with some WD40 sprayed on it. Wipe it out with a rag and you can get a better idea of what you are dealing with transfer and scratch wise. Then if you think it is transfer muratic acid will help desolve it. Carefully with a Dremel and a maybe 80 grit flapper you can get the aluminum out.

When it is all said and done you can see if you are satisfied or not. If you don't like the looks of it junk it. If you can get it slick as a baby's butt put a piston in it and go.

BTW. I have two MS661 cylinders that look about like that. I don't know whether I can get them in shape or not. But, I'll try.

It’s already missing plating on the bottom and top of the exhaust port. Both need opened up so that the plating at least reaches the edge of the port. Otherwise the rings are just gonna scrape more of it off

Yep.
