i just went to a go kart racing place to buy oil less then a week ago, they said they run like 40:1. The people who run 16:1 and fatter (like out on the go kart racing circuit) rebuild there engine before every race and they use that much oil to seat the rings fast. The motor life on those are like 20 hours at best.Kenny_McCormic wrote:Noting wrong with that much oil all you gotta do is install a bigger jet to let the gas displaced by the oil through.
If you look at people SERIOUS about making power(2 stroke kart racers) they run unbelievable oil mixes (usually 16:1 or fatter) given some of this has to do with turning 15,000 RPM but the dyno doesn't lie.
A man named Gordon Jennings did A LOT of scientific study on the 2 stroke motor back in the 70s. This is what he found out about oil, more oil=more power and CLEANER INTERNALS. http://edj.net/2stroke/jennings/oilpremix.pdf
http://edj.net/2stroke/jennings/ read it ALL, the 2 stroke motor really is misunderstood even today, blame the EPA and California.
I talked with the guy for a good 20 minutes about oil and oil mixture. He was saying on customers Karts or avg. karts they would use 40:1. * the bottle of oil i bought from the place said to premix at 50:1 right on the d*** thing.
I did read the first article you linked about premixing and i got to say it was very interesting. I have not had the time to read the hole book yet. And i dont plan on reading it online, i plan to buy a copy of the book myself.
You also have to remember that in the 70's there was no injectors and 2 stroke oil was very basic. New modern oils (the good ones, not that gas station s***) is not meant to be ran as thick.
There is no need to run that much oil dude. Just jet the d*** thing properly and use 40:1. *, ill even agree with 32:1 because i believe thats running a lot, but not to much. But anything 25:1 or fatter, thats just crazy.
IMO anyway...
