    Hi all,

    My 2001 WR250 is in need of a piston kit.

    I have spent plenty of hours trying to search for info on the subject but couldn't find any relevant info.

    Is boring out the 250 cyl to 300 successful? I did find that with the OEM 300 it runs the head with a lip. When assembled, where does this lip sit? Will the 250 head with the squish modified to suit still work regardless of the fact it doesn't have this lip?

    Appreciate any helpful input.
