For christ's sake. I met a girl in a bar said she hardly ever used it, practically brand new. Just buy a new motor.

Ya your right. 150 psi is pretty good for a engine that old. Maybe change the sprocket back to a 41 or 44. Like Ryderz said drop to 4 ozs. per gallon to see if it runs a little better and grease the gears lightly. If I knew how many miles were on it I might look at a couple of other things, but it could be that he did hardly use it and so tearing into it to replace the rings, wrist pin and bearing wouldn't be needed. Its a crap shoot.

Best of luck with it Pete...I'd say we covered the basics and about all that anyone can do online to help figure it out.
I would imagine being an 09 motor the crank probably vibrates like hell compared to most of the newer built motors even though they vibrate as well...vibration will kill speed if I'm not mistaken.
Having the exhaust ported to God knows what gasket and then using a stock tiny entry exhaust can't be all that good either.
Not knowing if your carb is tuned properly or not is another question.
Just run it and be safe for now...20 plus mph is already moving along on a bicycle to begin with.
