I agree, you need to have it checked out. In each of the 3 vipers I have had, the clutches have all been very easy. If you want to see what a hard clutch is, try one of the old big block vettes. Whenever I drive my brother's '66 427, I feel I've been through a real work out. Once I pulled down his driveway after I had his car out for a while, and told him to pull his car in the garage. He asked "Why don't you pull it in?", and I replied, "Because if I let this clutch out one more time, the car will wind up in your family room!".
