Should I rebuild it, 05 636
I just bought an 05 zx6r 636. When I looked at the bike, it sounded like a spun rod bearing, so I expected a complete rebuild or replacement engine. When I was pulling the engine, I found number 1 spark plug wasn't screwed in (no it hadn't blown the threads, just wasn't in). Since I only had a couple bolts to pull and the rest of the wiring, I went ahead and pulled the engine. When I got it on the bench, pulled the pan, and no signs of spun bearings. The only damage I could find was the seal to the valve cover on that cylinder got pressure, and blew.
My question for anyone that's done these engines. With 37k miles, should I do anything with the engine. (bearings, rings, etc) Or just put it back and see how it runs?
