Anyone used Amzoil 00w-40 in their WRs or YZFs? I'm hoping it'll help with the cold weather starts. My 10W-30 Yamalube is like mollasses and with the dry sump and external oil resavoir, I don't trust that it will stay thin enough to sufficiently lube the engine. I've also thought about wrapping the frame resavoir with insulation to keep the oil warm. Anyone ever do that to help keep the engine at operating temp?
