Who on here has repacked a header muffler? When I was at Mark's (TLRMan) place last week, he mentioned that my bogging issue might have been aggravated by the packing on my Two Bros system's muffler just aging. It is over 10 years old now. The loss of backpressure might have caused a leaner condition, adding to the bogging.
So, I've been thinking about repacking the muffler. Two Brothers sells a repack kit for $21 + shipping. (Two Brothers Racing, Repacking Kit)
Any thoughts?
