Re: in need of info
I can't help on the gasket part, I haven't had to go there (yet).
Taking the stock muffler apart to clean is pretty simple. Take the 10MM nut off the stud at the bottom, and the cap should slide out. The outer tube should come off pretty easily too. From there you could have one of several different internal styles. Brake cleaner is great for getting the gunk out, just hold the other end of the pipe over a bucket or something when you spray it in.
Any day that starts with a good ride is already a better day, and a bad day riding still beats a good day working.
