xr600 exhaust update.
I tested out my xr650l with a xr600 exhaust without the insert. It is a little loud for highway speeds. But with earplugs or headphone help to reduce the drone. On the trail it helped a lot with throthol response. I really think that it added more power to the bike. I am getting some popping on decel. Anyone running this set up did you have to rejet the carb? I have Dave's mod done rt know. But am thinking I might have to go up to 55/160 or 55/162.
