Banging noise from engine?

[QUOTE="Rhodester, post: 916304, member: 42241"] Although the normal KDX crankcase noise is pretty loud it's not piston slap. If you've heard piston slap you'd know if that's what it's doing. Piston slap is what you get when your piston is worn out and the clearance between the piston and cylinder wall is too great. It's cure is to replace the piston. I have a KDX200H with an FMF-30 pipe, An FRP pipe guard, and an FMF Q silencer. My crankcase noise at idle is greater than the exhaust noise even with a full quart of 10-40 or 20-50w oil in the engine (the manual calls for 10-40). [/QUOTE]
