Comments about FMF Powercore 4 Quiet Core Insert:
After a couple of months of listening to the bark from my KLX351 I decided that it would be a bit more responsible to quiet the beast. This insert does exactly that and barely impacts performance. Makes it a bit more enjoyable when I'm out in the woods.
Bottom Line Yes, I would recommend this to a friend
