I've got a 96 xr80 that runs fantastic unless you go quickly to full throttle. If rolled on its fine but if opened all the way quickly it bogs out completly. Any thoughts?

They don't have an accelerator pump on the carb. They can't increase revs fast enough in the transition zone when the throttle is snapped open. They lean out and die.

Try a larger pilot jet to aid in that zone.
