BTW didn't know I needed to be so specific if people have heard of it before. I bought a YZ490 clutch and the steels were right but the frictions were wrong. Thought it was a YZ400 or a YZ490 but didn't know what year or which model. I have a discount through Yamaha and prefer OEM. I am sure others who have been posting for an OBLIVION would share the same sentiment. Now I will crawl back in my hole because aparently my balls aren't big enough to be on this site. PEACE!!!!.
