I bought a 1994 KX60 for my nephew recently. I got it really cheap and it came with a new cylinder. The guy said it just needed a piston/rings/gasket kit, but I suspected bottom end issues because these 60's are known to for that. Upon tearing into the engine I found a bad crank; the lower rod bearing race broke and that is what fragged the top end. I hope to start ordering parts this week. The frame and swing arm are getting repainted OEM colors. This is not a restore, just a refurbish so my nephew has a good looking, clean running bike to ride.
I am looking for opinions on engine finish. Should I paint it, or sand/bead blast it?
At the guys house:
About an hour after we got home:
I spent about an hour the other day and finished tearing the engine down:
Bad parts so far, well everything but the oil glass I broke, lol. I was pushing it out so the cases were bare for finish and I managed to hamfist it and crack the glass haha.
