Did you do any mods that could have affected this? (Exhaust, jetting carbs, shimming needles, etc.)
Is the bike fully warmed up when you do this? Is the choke (fuel enrichment to please RedRider) off?
I know what you're saying is happening, the same thing happens with my weed wacker (don't laugh ahaha i can't drive). I don't hitnk anything is wrong with the throttle, because my weed wacker throttle opens just fine (i can see the cable and the actual throttle opening and closing).
What octane gas are you using?
Maybe the carbs need to be cleaned.
