    Not sure, i have a 2009 HT engine and the manual says 40:1 after break-in. Tho i havent run that engine yet. I usually run 25:1 tho next tank i will be experimenting with 32:1

    Wow,
    40:1 sounds iffy to me. I never recommend going over 32:1 after break-in and 16:1 during. Just my opinion, but, I've also heard the new, 09, motors are a bit different than the earlier ones in some respects so maybe the 40:1 is what they require. Still sounds dangerous to me. A little too much oil is always better than not enough. We'll have to see what the jury says on this one.

    At the very least use a good quality synthetic oil if you go with that mix. 30:1 would probably be safer! The motor depends on that oil for lubrication.

    With Amsoil Saber, sure. It's designed for 50:1 with motors like these. Most other oils, that might be pushing it a bit in the heat, on hills with a heavy rider going WFO.

    no,do not use 40:1
    what are you trying to save a few cents on oil,
    hope you carry a extra $100 engine with you.

    first of all, in the ratio 40:1, the 40 part refers to the GAS, not the oil, so a 40:1 mix has more oil than a 50:1....I run about 60:1 (less oil) with 91 octane and synthetic oil...my buddy has a racer that he runs at 100:1, but this is for short track racing and not for distance. I ran a 50:1 mix for the first 300 miles and my spark plug was blackened, since I thinned out the mixture, it has more throttle response and less incomplete burning....a 30 or 40 to 1 mixture will have oil dripping out your exhaust.

    25:1 Full Synthetic Is What I Run. All Depends. Run 40:1, See What Happens And Keep Us Posted, The Motors A Cheap You Could Just Get A New One. I Plan On Beating The Crap Out Of Mine In Due Time. Fire It Up And Beat It Down.

    Right... I'd Probably Go With What Pablo Said And Get The Good 2 Stoke Oil, Than You Shouldn't Have A Problem. Fuel Mixture Is Always A Rocky Subject Cuz Of The Difference In Opinion...

    The thing people seem to miss: It depends on the oil!!! Amsoil Saber 40:1 you can run all day 40:1 and almost be on the edge of too oily. Kmart special oil or whatever and maybe not so much.

    How Bad is oil that is not detergent oil, I have not been running detergent, Last 2 quarts have been Valvoline, 2 Cycle. Multi purpose, I was using a mixture of 30-1 and changed to 35-1, =4.5 oz. oil, it was hard to start now can't start at all, might have become worse as the previous tank empty out and was replaced by the 35:1, Sounds like these guys are running pretty dry gas, but Kings recommends 20:1 first gallon, Can't figure this, not starting, getting spark, should be getting fire, Not getting the slightest. Didn't know that these engines are so finicky or maybe that isn't the problem at all ?

    Looked at the Cylinder through the Spark Plug hole and see speckled Top of the Cylinder, looks kind of light Tan and black Speckles ?? Anybody have a clue ?

    "detergent" oil is pretty much a meaningless term. A good oil mixed at 30:1 or 35:1 won't hinder starting. BTW 4.8oz/gal is 28:1.

    20:1 with a good oil will be WAY too oily. Trust me on this.

    Are we on the same page, . . Correct me if I wrong, 35-1is 4.57 oz to the gallon, right?

    1 Gal=160 Fl. Oz. / 35 = 4.57, That's 35 to 1 Isn't it ?

    Per King's
    Break in ratio for 80cc is;

    20 to 1,= 06.4 oz.
    Synthetic 2 Stroke Oil per 128oz,;gallon gasoline.

    After the break-in period, the ratio is increased to to 35 parts gasoline to 1 part oil.

    30:1= 04.26 oz.
    31:1= 04.12 oz.
    32:1= 04.00 oz.
    33:1= 04.12 oz.
    34:1= 03.76 oz.
    35:1= 03.65 oz.

    Hey wait a minute, let me check, I swear to you I was at a conversion chart and have read 60 Fluid OZ per Gal. !!
