That's not much of a change, now is it?I start off at 24:1 and go to 24:1 later.
I would imagine your chain saw, or for that matter almost any small 2 stroke engine was built to a little higher specs. than these Chinese Bike Motors. There is NO quality control.Ok something I don't understand. Why can I run a chainsaw or weedwacker all day long wide open at 50:1 yet this engine requires insane amounts of oil? Can't I mix the gas leaner and adjust the carb richer?
4 oz of oil to a gallon is what I recommend once they are broken inWell I plan to run 30:1 wal mart oil or whatever I can get my hands on. I am driving this chinese junk to work 4 miles one way every day to save loot. I think we should report back to this thread with longer term results. BTW 32:1 wal mart oil = no smoke.
This is soooo true. My kit instructions said to run 16:1 for breakin, and talking to others and reading posts, this is because the oil they use in China is 30wt motor oil which is much thicker than modern 2 stroke oils. I did my breakin at 16:1 then shortly afterwards went to 32:1 using a quality oil (AMS Saber) and have well over 1000 miles on my engine with no problems and runs VERY good...........The thing to pay attention to (and most people don't) is what the oil manufacturer recommends when it comes to 2 stroke oil. In simple terms, some oils are more concentrated than others.
I started with 50:1 many years ago because I had more than one engine and wanted to see. After a few thousand miles with no problem I decided to do it with all of mine. Now 6+ years later that engine has 14k on it and just starting to lose compression. Many bikes put together for myself and others since then also 50:1 and not one seized or bad bearing yet. Maybe just lucky. Or maybe that 20:1 stuff is because they use motor oil in china. And half of it drained from a car. I have watched them do it!Ok something I don't understand.
