Cylinder head repair

Any recommendations on reputable options for cylinder head repair shops? I’m pulling the head off my yz250f that has a blown head gasket.

 

I’m hesitant to ship it off to someone without a recommendation. I won’t have specifics of what it needs until I pull it off, obviously. But just trying to get ahead of the ball.

 

(Bubbles in radiator when I start it, white smoke from the exhaust, hard to start, hard to keep running, and oil looks funny. I put fresh oil in, drained it, and it came out kind of dark with a whiteish tint as well. If that makes any sense?.)

 

Thanks.

Hopefully it’s not metal shaving in the oil. But if it is, it would be extremely fine metal shavings. I may take a closer look at the new oil filter I put in as well.

Blown head gasket is a blown head gasket.  Replace the gasket.  Simple.

That’s my hope. I can’t help but plan for the worst though.

Where are you located? You'll want to get a reading on flatness on the head instead of just putting a new gasket in it. If the head or cylinder mating surfaces are not flat, you'll be doing this all over again soon.

Agreed! Davenport, Iowa.

Klemme Performance. Have them check the head and top of cylinder for flatness. 

I’ll look them up. Thank you!

Lindsay Machine Racing in sandy Utah is a really good one!

I’ll check them out after Klemme. Can’t beat the convenience of not having to ship. But thank you!

Yea I understand I wouldn’t want to pay $40 to ship either!

Call any local machine shop. All you need to check flatness is a granite table and a .002" feeler gauge. It's simple.

Awesome! Thank you!

Thats a rough way of doing it. If you look in the manual they use a straight edge with feeler gauge in various positions.
