20:1... (it works for me!)

20:1 and even as rich as 16:1 is ok. But do it for 2 gas tanks. Your bike will be a little sluggish, but it will make your engine run beter in the long run.

I'm running 16:1 right now, "Universal 2-Stroke Oil" from Wally-World. I've got to dump the tank today because I mixed outboard motor oil for this can, THEN read the thread on why that was Not A Good Thing.
Performance is not anything to cheese about, but it *IS* improving as the engine parts get to know each other. Next tank will be less oil.

Depends on the oil. I sound like a broken record!!

24:1 is plenty oil rich with some oils, WAY too much oil with Saber.

I've been running 16:1 with my break in. I'm using Lucas semi-synthetic "smokeless" oil, and it ain't smokeless at 16:1

. Smokes quite a bit actually. But I'll be through my first gallon soon, then I'll see how it does at 20:1.

But yea, 16:1 seems like the norm for engine break in.

alot of this shops will tell you not to run 16:1 because it will ruin the life of yur engine when you are breaking your engine your are supose go with 20:1 for the first two gallons and then go with 32:1 if you go to usabikemotors. they have a chart of how much oil to use i get my oil from the hame depot is call ryobi its really good oil well good luck raul

This is just what I used, it worked for me my motor runs great I have over 700 miles in 4 months. I started with regular not synthetic oil for air cooled motors. 8oz/gal (16:1) first gallon, then second gallon I went to 7oz, third 6oz. Then I switched to synthetic oil, 5oz in my 4th gallon, 4oz (32:1) ever since. I still have a little oil residue in my exhaust so I think it's lubing well. It runs strong and fast.
