Well i was out driven the storm around and noticed when i hard excellarate there is this grinding noise. Smae thing when i stop. So i inspected it and nothing. Well my one way was slipping so i took apart the engine to wipe it off. #1 the pull start on the stock storm is not sealed so when i pulled it off........ BOING. Well after that i get into the engine to find a few abnormal cracks in the con rod here in there and the pistons sleve torn to hell. New piston sleeve time or new engine time. I'm looking at the new p5, ws7 2, or sirio .21. Well just thought i would share my experince with everyone.
