I recently bought a KR150, which is great but it needs transmission oil. Do I put regular 4T in gearbox and 2T in fuel or is there some special gearbox oil for 2 strokes?
Go to a motorbike shop and ask them for some 2 stroke gearbox oil. Use fully synthetic 2 stroke oil for the engine.
I've always used 4t gearbox oil in all my strokers (and there have been many) Also I dont use full synthetic in the gearbox .
