286/7Used OEM Nikasil cylinder (with powervalve) from a 2002 Yamaha XLT800. This is OEM niksail (which means STD and it CANNOT be bored). It is not burned out, but you can see some pock marks that show through in some of the pics. You can give this a light hone and see where it leaves you.  But ultimately it is sold as a core with no guarantees and may need to be re-plated. There is also a broken bolt in the exhaust mount on the rear of the cylinder. I guarantee all our parts to be as pictured and described!
