250x valve specs and comp ratio ???

[tinner]

I'm putting the 250x back together and need to know what the valve clearance specs are. I have a book on the 300 ex, But I'm not sure if specs are the same. Also, I'm curious if anyone can tell me the stock compression ratio on this beast. Thanks

Hi Jim,

The valve clearance on both intake and exhaust is .004. Compression is 9.4:1.

Hope this helps,

Thanks for the info.
