[dsn_klr650] a serious question

[JD]

Thanks Karl, It is like you described, no gunshots....When I get the new exhaust, will re-jet, and hopefully will start to sound like something other than my craftsman mower. JD (Mr. Popcorn at low rpm's, but lovin every minute of it) a14-1.5k Karl Raupp wrote:

If you haven't done it already, you have to drill out the brass plug covering the mixture screw (on the bottom of the carb), and adjust the mixture screw to get a richer idle mixture and this should cure the backfire. Jake Jakeman, Sagebrush machine, makes a tool for adjusting the screw. Search the Archives and check out the DSN web site for details on this procedure. Jeff

You motorcycle skills make you a better driver too. Think about it; situational awareness, visual scanning habits, alertness. These skills are formidable for safety behind the wheel. Most people get into their box, crank up the stereo, bust out the cell phone, slap the brats in the back seat, and space out when behind the wheel while tailgating the car in front of them. Jeff
