i just can not believe this cheap motor is still taking the abuse !!! srsly i need to document this !!!
how many rpms do race motors turn ? how many rpms are concidered safe for the china girl ? because i am dead shure i am turning well over 8,000rpm's ever ride and keeping her over 8,000 for 99% OF THE RIDE
With your mix at 21:1 they can be hard to hurt.
You are making 40:1 fuel by adding 3.2 ounces of oil per gallon. Then you are adding 1.5 ounces of high grade synthetic (Lucas) per half gallon, which brings the blend up to 6.2 ounces of oil per gallon, or 20.64:1
High performance Karting engines run between 16:1 ~ 24:1 Plenty of oil will keep a 2 stroke alive under very harsh conditions. A chainsaw of similar stroke will turn 13,000 rpm @ WOT for most of it's service life.
