You're preaching to the choir here with your stories. I'M the guy everybody brings their weed whackers and two-stroke stuff to when it doesn't work. "It just quit, can you take a look at it?" One pull on the starter cord and a look in the gas tank is all I need. If it doesn't pull and the gas isn't blue then 9 out of 10 times it was straight gas. I've gotten to the point where (because of lost time taking things apart to discover the inevitable)I tell them "Sure, but it will cost you $20 for me to tell you what I can tell you for free right now". No one is willing to admit they ran straight gas (at least not to my face). Some actually pay the $20 just to look at the scored cylinder & piston! The replacement parts manufacturers basically price their parts that, when labor is included, people like me can't get work. It doesn't make sense to repair at 50% of the cost when you can get a new one (with warranty).......and remember to add oil.
A few minute run on a two-stroke motor is how many un-lubricated strokes? Hummm...2500rpm x 3 minutes= 7500 revolutions. The lower bearings and rod bearings will take it on a HD lightweight. The seals are a different story. If the piston seizes then it's over-bore time and cross your fingers with the other stuff. I never pre-mix....it's easy to forget. If it's a two-stroke I put the oil in first and then add the gas and 'shake'. This way I KNOW it's done.
Note to the Ad placer: If it ran on straight gas why did Harley still put the oil cup on the gas cap?

I was looking at this ad and discovered something i didn't know -

"This is a 165 motor. The easiest way to tell is that the 125 requires a gas/oil mix and the 165 which this bike is, only gas."
