I just got my quad bored out .20 with a new piston because I crack the stock one neways now I have to break in the engine and im not really sure what im supposed to do.
 
my clymer manual says first 10 hours 1/2 throttle or less and next 10 hours 3/4 or less throttle after the 20 hour breakin go crazy and tread lightly
 
there's a thread in the diy section on breaking in a 2stroke.
i've done this 3 times now. the first time i just rode her kinda easy for the first 20 and the last 2 times i went through the heat cycle method. it's much quicker and my compression seems perfect.
