Got a KLX300 pipe a couple of weeks ago from fellow forum member "donaldor"

Had some time today to install it, 30 min. later, a perfect fit, no adjustments needed....I was very surprised.

Anyway, the exhaust note is music to the ears.....just what I was looking or hearing for. Test drive, not sure it had more power, but who cares, it sounds great!

anybody have any suggestions of jetting? most of my riding between 4,200 and 11,000 ft. I live at 5432 ft.

 

Have you already jetted the carb before ? The KLX300 exhaust is basically identical to the 250 cept for the removable butt plug (which should help power somewhat) but that's not drastic enough of a change so I wouldn't think jetting would need adjusted at all if it was already properly jetted in the first place.
