FMF Stroke Muffler Packing
- Repack your muffler regularly for optimal performance.
- Repack your muffler every 20-30 hours under normal use when properly jetted (more frequently if jetting is rich).
- Packing is often neglected though it is necessary for a properly tuned exhaust.
- Always repack your muffler if water enters into the chamber and saturates the packing.
- Cover or plug the exhaust outlet when washing your bike or ATV>
