After running 20,000 kms my KTM DukeвЂ™s sound has changed, how can I make it as it was before?
Bike’s sound is controlled by the muffler and the exhaust system. The muffler is the main component that controls sound, we suggest you the following things to fix your bike’s exhaust sound:
• Check the baffle whether it is in good condition, if not then replace the baffle with the same kind or choose an upgraded baffle. (Inside the muffler chambers, the baffle is a perforated tube that acts to deaden sound waves. Over time, the baffle’s performance declines and sound increases.)
• Tighten all nuts and bolts which hold the exhaust pipe into place and you should find that the amount of noise has reduced.
• Check your exhaust pipe for leaks, which can produce large whistling noises in the exhaust pipe. Use epoxy putty to fix any leaky areas as this will solidify and form a strong barrier over any cracked areas. This will significantly reduce noise and prolong the life of your motorcycle exhaust.
• Finally if nothing works then reinstalling the factory mufflers and pipes is the easiest way to fix the sound.
