Hello guys I am doing a top end rebuild on my 07 yfz450 because when ever I would change the oil the oil would be very milky. So I don’t know if my cylinder is bad it looks like it has a few scratches but they are not deep.

Would you guys buy a new one or just run it like that or hoon it out

if you have it apart you might as well do it right the first time and have it honed.

If you can catch your nail on it I would replace it. If you can't maybe a hone. For me I would just replace it but I put alot of money into my machine. It really up to you.
