tweeting muffler

[Andre Roy]

Hi, I was enjoying the good weather this weekent when I've hit the 12k km on my klr's odometer. What a surprise, a new sound start happening and seem to come from the engine. I've try to diagnose it but it seem to only happen when the engine is on load. I'm not a freak, but after reading all the messages in the klr mail group, I'm sure I cought the tweeting muffler syndrome. Is anyone please may take a picture of a well done " muffler drilling job " and post it on this group? 99 LRK ydnA laertnoM
