Muzzy Exhaust: Difference between revisions

Line 18:

Without meaning to discourage anyone from trying, it's probably more trouble than it's worth to keep it. You can buy a nice swingarm stand for about $70-100 though, which will let you do most of the maintenance the centerstand allows. The only time you'll probably still use the centerstand is when you're doing rear suspension work; the stand can be loosely attached temporarily with two 17mm bolts, and put back in the parts bin when the work is done.

~~====How do I repack the Muzzy?====~~

There is a kit available from [http://muzzys.com/ Muzzys] for repacking the insulation material in your muffler. It's about $25. You'll need a pop rivet tool (about $10) and rivets (1/8" diameter, ~3/8" length) to put it all back together. The end caps are stainless steel and are reused.

The repair kit consists of the perforated inner tube wrapped in fiberglass. If you could get the right fiberglass material from a muffler shop or auto parts store, there is no reason you couldn't just replace this bit. Look for material for automotive glass pack mufflers.

What you'll most likely see when you open up the can is that what little fiberglass is left in it has settled to the bottom half, so there is no sound absorbing material at all in the top half. (And you were wondering why it was so loud.) With the new packing, the bike should be quite a bit quieter than it was. Still loud, but tolerable.

~~To install this, you have to drill out the rivets and remove the end cap (sounds simple, but it's awkward and takes a bit of effort. One member recommended seeing if Muzzy would do this for you.)~~

~~Only one end cap needs to come off, and the engine side cap is easier to get off, since the mounting hardware provides something to pull on.~~
