Just change your oil when you are supposed to and you won't ever have to "clean out" your motor.
I have torn down my share of Mod motors and two 3v's now and even ones with a lot of towing miles (truck) all looked brand spakin new. Even the truck motor that I towed with and din't change the oil for 30,000 miles.
