Yamaha pistons come pre drilled. Oil all depends on what kind of riding you do. If racing mx then 927 or klotz something with castor in it. If just trail riding then something like superM works good.
@@thetwostrokerebuilder so you would recommend old school castor for powervalve 2 strokes bc that's the only reason I run bel ray h1r seems like the best full synthetic money can buy & will keep powwervalve from sticking. Is that why you need it for racing to get the temps up & burn off carbon?
Good video, my new piston has no holes im pretty sure, glad you showed me this.
What 2 stroke racing oil do you reccomend or have you had good luck with / engines look good
