In this video I’m working on my 1992 Polaris SL 650 triple jet ski. I had low compression and while digging into it, I realized my lower cylinder gaskets were blown out, possibly by ice.
I also find out that the engine is an SBT aftermarket 650, with good looking rings and nicely honed cylinder walls. I don’t end up doing honing or the rings.
It’s not an exciting video, but if you have an older 650 triple, hopefully this is helpful!
