Today I bought a "British shorty muffler" thinking that, at twelve inches long, it will be easy to mail. I can't for the life of me figure why, after all these years, the stock bikes are coming out with such a huge muffler. Makes for a good after-sales market. I figure it will end just past the rear foot peg, far enough back I hope. It was only 26 bucks so I'm not out much if it doesn't work out. The photo of it looked pretty nice.
So, using the resources of internet, my total outlay for an open system - K & N filter, Mikuni main jet, and less restrictive muffler will be about fifty-two bucks plus about that in total postage. Think my old Scottish ancestors would be happy, maybe more so if I could just wake them up from the dead!
