Swirl Flaps within your engine deteriorate over time and can end the life of your engine!
Designed to produce a swirl of air to aid combustion when the engine is under light load; the flaps are held in place by two screws, unfortunately as the swirls move over time these screws can loosen or the spindle making their way in to your engine.
This in-turn can do a number of things; jam open the valve port causing the piston to collide with the valve, enter the cylinder itself ending the life of the engine and even after leaving the engine further damage can be caused to the exhaust system
