2001 yz125 "I bought this cylinder kit to upgrade from stock. Heard alot of good about them so i decided to try it out. The cylinder kit came with everything you need from the base gasket up to the cylinder head. I love the dome insert design. I think it allows for maximum cooling of the cylinder head. And if the dome gets messed up you can just buy an insert istead of a whole new head. Port matching is great. Everything fit exactly as it should. Ive ran one tank of gas through the bike for the break in and it runs sweet. NOT a cheap kit not gonna lie. It is cheaper to have your cylinder repaired or bored. But things last longer at stock bore. And hey. It comes with stickers! But overall i give this a 9/10. Definitely would recommend. I am verry happy with my purchase"
