top end break in
My RM turns a year old in a few weeks so that means time for a new top end. I purchased a Wiseco ultralight yz250 piston part #808m06640. my question is how long should I break it in for I have done it a few times I just ride easy for a tank of gas usually riding for 20 min then letting the bike cool down then do it over and over giving it more throtle 1/8 1/4 1/2 ect each time but I have heard let it warm up and baby it for a little while and its fine and mxa said they ride easy for 10min and then forget about break in and the bike is fine
