Breaking in new top end

Ok lol i just got on this site because ktmtalk has been crashed for a couple of days now and i need some info on how to break in your new piston.

Well i just completed a new top end on my 200 exc 04. I was wondering what is the best way to break in the new piston?

Oh yeah and when you aplied a new gasket to the cylinder do you put any gasket maker or any thing like that on the gasket or do you do it dry. lol thanks

gaskets go on dry. Put it through a couple heat cycles, bring it up to temp and then let it cool completely down before doing it again. Then just take it easy for the first tank.
