Hey all. I have a 97 Xr600. All Stock except a slip on white Bros E series pipe. The bike Hesitates/bogs when the throttle is 3/4 open no matter what gear I am in. I have cleaned the carb completly 2 times. The temp is 100 on avg, ALT 2200 ft ASL. I just want to get ridding again. Could my valves need adjusting? Have not had them done in years. Any help would be great.
