Hello thanks for the answers. I worded my first post wrong the head is orange not blue and is a MVVS engine. I also race motorcycles
I think one of the last few holding out and riding a 250 2 stroke MX bike (LOL) I use Klotz Supertechniplate 2 cycle premix. Is this a good oil to use in this engine? It is a full synthetic with %20 castor added, I can also easily use R-50 Klotz which is a full synthetic but in my motorcycle applications I see less wear with the Techniplate, but I use my bikes for racing so they are ridden hard and all oil deposits are burnt clean. Also what is a good brand 18x6 prop?
