No matter what version of phantom 85 you have. If you still havnt deleted your reed and installed a solid piston. You are playing with fire. Piston slap at WOT is still destroying motors. Im a member of many FB groups and forums and I see atleast 1 post a week where a p85 self destructed. The stroke of the original sthil topend is 36mm to 38mm stroke. this topend does not like to be on a 40mm stroke with a windowed piston. MAINLY THIS HAPPENS AT WOT. but whats the point of all that power you bought if you cant tease it wide open. Delete thoes reeds.
