    So I chipped a piece off my powervalve regulator. Straight on ebay on bought another and its got a different spring on it. Its alot stiffer than the original. What will this do to the performance? More top end??

    check the bearings they may be a different size and weight, if not just changeout the springs to keep it stock.
