He took some bad advice from someone as gospel - "all you need is a 50:1 mix with this monster-power synthetic oil, and your bike will make HUGE horsepower". When I heard about it, I instantly new that 50:1 was way to "thin" for a race bike, especially the way my nephew rides. I can understand that my factory manual spec of 20:1 is for all out racing for which the bike was designed. But that would have me puking oil out the end of my silencer.
