I'm not exact on putting oil in my mixing jug lol

I'm using full synthetic stihl HP chainsaw oil at about 32:1

I would personally reduce to 40:1 and lean out the jets accordingly, but if it's running fine then there's no reason to change.

That's about what i thought

30:1 synthetic is good for extreme use like keeping the engine at top RPM for a long run.

I'm either full throttle or idleing, usually no in between

actually 40:1 is OK for these engines because max rpm for those without the exhaust port raised is no more than 6000.
synthetic is nice for its lack of smoke, no drooling out of pipes, and lack of residue left on engine parts.

I've raised exhaust
So I guess Im just about right

Plus also from what I've heard the 2015 model skyhawk would easily revv to 8000 RPMs, I know it doesn't vibrate as much

yeah and I've also heard they can go 50 miles an hour.
so I highly doubt that claim.

I know that's not true with the sprocket it comes with, since it is a 48tooth lol
