I got Yam 200cc ATV Blaster, it has a 2 stock oil reservoir to mix in with the fuel. I was riding flat out when for a moment it lost power. I stopped let it cool then continued on much slower. I guess it wasn’t getting enough 2 stock oil? I went to Yamaha and asked them…"It user as much as it needs” (he must have been factor trained). I measured of the oil bottle, kept a log of fuel and oil used over time. I am using 100mm of oil to 10 liters of fuel, ie 100:1 mix. I asked my friend he said Yamaha Outboards used 100:1 mix but he could tell me if that was normal for my bike?? Have I got a problem with the oil pump? How much oil dose the blaster use?
