OK, I blew the piston on my 94 YZ 125 this weekend. Pulled the cylinder and there was debri in the crankcase. I vacumed it out, blew it out, vacumed again, blew again.....you get the idea.
I am confident I removed any debri, (there wasnt much to begin with, just some fine sparkles) and the crank moves freely....
Question..can I put on the new piston and cylinder and go with it, or do I need to split the case and clean each part. Is there a way I can flush the case for good measure.
I have never split a case before and am not wanting to if I dont need to.
Thanks for the help, I am glad I found this forum.
