sounds like your clutch is locking up. it could be because a spring broke inside the cluch and is rubbing up against it forcing the clutch to engage. thats what happened to me. i had a ACT stage 2 on for a while that did the same thing, and i guess it just got old. but, since mine would not stop engaging, i just roughed it all the way to my friends shop. he swapped the clutch for a new one, and its great now :] although its a stock one now
