I have the strangest problem:
Three times I have placed my 2009 S40 on Craigslist and Cycletrader, to sell.
Each time, I chicken out and pull the ad after a week or less.
I try to get rid of this bike. But, every time I ride it, it cracks me up. It runs great and loves to backfire on shutdown. The backfire alone is worth the price of the bike. ( I usually look for potential victims before I turn the key off.

Great fun!)
The old girl turned over 13K today. Will check the tensioner at next oil change.
I did mod the pipe. I cut out the guts, on the end only, and then got a big flat washer from the hardware store. I found a 1.25" to 1.5" exhaust reducer at Pep Boys, welded a steel freeze plug on one end. (I had to grind the washer hole to fit the pipe and protruded it about a .25" through the washer.) I filed the outside of the washer and made it interference fit the end of the muffler. (Did I mention I drilled about 40 small holes around the reducer?) It sounds great and runs good. Also took a little off the white spacer in the carb. Other than that, it's stock and fun as Hell.
I'm still looking for another bike...
But, I think my little thumper is safe for now.
Back to lurking,
Mike
