That chrome trash can Suzuki calls a muffler is heavy.  The Dyna muffler is a better visual fit and weighs less.

That's just the way that black ice will do ya.

I saw an old dude let the rear tire roll over the end of a tar snake on a hot day. The taper of the tar just slid the bike left. He was just sitting there, rolling along, not acting a fool, and on his side sliding down the road. He didn't even have time to get a foot off the peg.
32 feet per second per second is Daggum Quick, innit?

Thanks again to everyone for their input.  I started a few "easy" things today.  As I get further along, I'll post a build thread... assuming I build it into something interesting.

If you're trying to increase performance, start with timed runs.
Or you won't know if something helps or not
