hello,
bought a 2012 yz125. used klotz benol caster racing 2 stroke oil for premix 32:1. did research on premix apparently caster oil gums up valves? dont want to have to open up the motor/carb to much not very mechanically minded. thinking of using klotz techniplate. what do u guys use and why? also heard good things about amsoil, motul, and redline. please respond would like to order soon?
