I have a half fairing 47cc (40.2) samurai pocket bike and in the manual they say to use 25-1 for the first 5 tanks,then after break in, use 50-1.
i use powerstroke 2 stroke oil,and have been told (off one of my mates)to only go to 30,35-1 oil mix(after break in period) in fuel.
Is this better than 50-1? |
