Cylinder head repair

14 posts in this topic

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.

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

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

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.

      Rockstar Energy Husqvarna Factory Racing Star battles Through All-New Format Hell’s Gate to Finish Second
      February 11, 2018 – (Motor Sports Newswire) – Rockstar Energy Husqvarna Factory Racing’s Graham Jarvis has earned a strong second place at the 2018 Hell’s Gate extreme enduro. With an all-new format for this year, concluding in a 20-minute sprint race, the event posed a fresh challenge for the five-time winner.
      For the first time ever, the event kicked off with a Prologue race on the Friday night. Designed to set the starting order for Saturday’s race, the Prologue was an endurocross style event held close to the hosting Il Ciocco Hotel. Although it provided a great spectacle for the fans, the race results were eventually scrapped due to issues with the course.
      Saturday’s heat race went well for Jarvis. An expert at managing his pace, the Brit did exactly what he had to do over the five-laps, finishing fourth aboard his Husqvarna FE 250 in the cold conditions of the Tuscan hills. The position gave him a good start for the night race, which saw riders set off at 3.30pm for a tough three-hour multi-lap event.
      At the conclusion of the night race, the top-10 riders were given a 15-minute break before contesting the new 20-minute endurocross in the arena area of the venue. In freezing conditions, the riders fought bar-to-bar in front of the record-crowd of spectators to decide the overall winner. With the final results calculated on the sum of the previous legs, Jarvis was announced as runner-up, just a few minutes behind eventual winner Mario Roman.
      Graham Jarvis: “I really enjoyed the racing today, I always do here at Hell’s Gate. It’s been a tough couple of days and I’m still getting used to riding the 4-stroke, but the bike has been absolutely faultless over the entire weekend. It has been pretty close between the top-four all day and it’s all come down to the final 20-minute race off. It would have been nice to take my sixth win at the event, but I’m happy with second.”

      My top end went on m 98 cr 125, the needle bearing clip came out and broke apart and shrapnel got everywhere and blew it up. I cleaned out the top end and washed out the crank with the bike upside down. the bike starts up great and seems to run fine but im getting a weird di-di-di-di-di-di-di noise coming from the motor. i tried adjust the power valve and tightening everything but the noise is still there. Here is a link to a video where you can hear the sound. It gets louder as rpm's get higher and at really low rpm barely idling it goes away. I am pretty new to bikes and 2 strokes so any help would be appreciated.
