Toldja to pull that cylinder, didn't I ?
>>(1) I better break down and buy a muffler, before the neighbors call the cops.<<
Bi-Turbo is the way to go, get the two piece.
>>(3) I'll have the cylinder honed, get 2nd oversize rings and a new piston.<<
The only dude I know of that bores Moped Cylinders is this place.
And even with Wysco, I have not been able to find a piston that small, but ask him, cause he just might know....
