[xrdavid]

guys do any of you know any ways to modify and squeeze some better performance ot of a 90" xr80 without spending much $ ?
if you do, please post. i'm putting an fmf powercore4 on it and i'm experimenting with different sprockets.

Sounds like what i'd do to a 4-stroke

You could try to find a XR100 motor It'll bolt right in without any mods.
Also the XR100 has a bigger carb.
Try to find a 1992 or new motor because it has CDI ignition.
