well, i fired it up yesterday after i adjusted the valves, and it sounds way better and seems to run nicer, i also adjusted the idle air screw, since the kid had it 2 1/2 turns out, and factory is 1 to 1 1/4 turns out. seems ok now.
only thing i noticed was the first time i started it up it smoked a good bit, it didnt do this before, so i'm wondering if the valve seals are just ****** up and it took until i adjusted them to where they should be to act up? i dunno. i'm gonna fire it up when i get home from work and see if it smokes a lot, that should tell me if it is the valve seals or just a freak thing.
