Is repacking your muffler every 5K miles a thing? I don't think I have ever repacked mine on my 2003 CBR954RR in the 15 years I've had it. But the end cap is scratched and missing paint, so I wanted to replace it. TBR charges $65 for the endcap but $100 for a repack kit, saying you should repack every 5K miles. Makes sense, after 20K miles, to get the whole kit, which comes with an endcap. But I don't have a rivet tool and Fay Meyers says my bike is too old for them to work on.
Is this worth doing, either myself or getting a local shop to do? Thanks for your input.
