   Just fitted the race head to my 300, I won't have a chance to ride it for a few days but it has raised the compression from 155 to just over 180 psi. As someone else said it probably isn't necessary to improve the performance, but it is a disease which can only be cured by tinkering!

   Can I bore a CR 250 (2002) barrel to fit a 300 piston? Where should I send it?
