[QUOTE="James, post: 139098, member: 2"] You will not get 100 hours out of a 250f piston, they're rated for no more than 50 hrs and that's if you're a slow poke like me. Most replace them at 30-40 hrs. Fast guys replace them around 20 hrs. Valves though will last you over 100 hours. :thumb: [/QUOTE]
