Hi Benji...If you use Yamalube 2B, you should do so with a high rpm engine, with high compression. Again, they will not give details, but from experience that means 12,000 rpm and higher. Compression ratios above 10.5.
That is why I imply, you cannot go wrong with 2S. It has the broadest temperature curves and works very well in hot climates in either pre-mix or pump. Personally, I think all 2T oils don't do well in hot climates on the pump.
I pre-mix and adjust to conditions when needed...It's hot here always, but we can go from sea level one day, then jump up to over 2500 feet or more elevation. Humidity from 45% to near 90%. BTW, I do not adjust ratio...I painfully adjust the carb.
Don't get me wrong, there are oils as good as Yamalube, but I find full synthetics more consistent with less down side. (Except cost)

A blip is a quick roll on and then off of the throtle. Try going to a poersports shop or site, or an oil company site (I.E. Amsoil..) And look for the gallons. EBay and Amazon also have late containers of good oil at times.
