Used part with low hours. There is a small mark inside the head. They guy I bought it from said there was no issues when the bike was running. He was just parting out the bike. I did notice that the area where the small mark is the surface is a little flatter. I don’t know if this will cause any issues that’s why I’m stating this. Let me know if you have any questions thank you. Part number # 12200-KZ4-L10 CYLINDER HEAD This part is no longer available to buy new.
