5/2008 These are from May 2008, it's just rolled over 2500 miles.
The 650 single of the S40 (or Suzuki Savage) is tuned very lean so it can make emissions testing. One of the issues that arises this is the pipe turns very blue unless the carb is rejetted. On mine, it's still stock and there's a little blueing of the pipe but not that much:
The bike's fuel system is still 100% original but there's still not much more blueing on the pipe, it's more of a golden color and has stayed that way since 2500 miles or so. There's now a brown patch on the pipe just behind the head shield though.
It still has the OEM IRCs on it but they're getting thin:
Since one of the reasons I bought the bike was because of the increasing costs
of gas, I've kept track of the gas mileage it gets since it was new. The only thing missing from the total I've spent riding the bike is the $129 I spent for a 600 mile service.
I've switched to using fuelly.com to keep track since the spreadsheet was becoming too cumbersome. Here's my badge:
