I am breaking in new vito's 240 ! I also took off the oil tank and will start mixing the gas BUT not sure what ratio to break it in ! I saw somewhere that it should be a bit leaner than normal !
most run 32-1 some 40-1 ive heard you want to mix your gas/oil the same when you break it in as when you are going to ride it. i would definately say you dont want to run it leaner.
