I did the same thing a month ago. The part is $10 at the dealer. --------------- Dennis Steinert 1999 KLR650A dennis@... -----Original Message----- From: Weaver, Mark [mailto:markw@...] Sent: Tuesday, June 27, 2000 13:48 To: Klrlist (E-mail) Subject: [DSN_klr650] chain adjuster plate? do other models fit klr? after changing tires the other night, the chain adjuster plate (on the back of the swingarm) ran away on my first commute to work, along with the two nuts and 1 washer that hold it on. anyone else lose one of these and discover that some other model also fit? i'm heading up to cyclesalvage this afternoon to see if i can rig something up without ordering the part new. mw ------------------------------------------------------------------------ Whassuuup?! http://click.egroups.com/1/5996/6/_/911801/_/962140152/ ------------------------------------------------------------------------ Visit the KLR650 archives at http://www.listquest.com/lq/search.html?ln=klr650 Support Dual Sport News... dsneditor@...

This topic never goes away, just rests for a while.

This would not be unique to thumpers. Any motor can have a flat spot under the right conditions. The longer the duration of the cam timing the more likely it is to find a flat spot, although an exhaust system designed for peak power is a common bolt-on flatspot generator.

Also affected by the exhaust system dimensions.

A small change to a carby setting might eliminate this, like float level, main jet or needle, or maybe a change in the exhaust system. Symptoms of overlean running are not unknown on more recent bikes. Most recent vehicles are set up for mixtures a bit on the lean side when on cruise. A small variation in the carby could send the mix a bit too lean. Mister_T
