Alright, see if you can follow me. I did a few things to my 1997 XR600R and now it's running like crap. I cut the side panel at the airbox and replaced the stock filter with a twin-air. The bike also has a Yoshi pipe and 65 slow and 165 main jets (which were in it before the airbox mods). When I start up the bike with a new plug it idles fine until I give it some throttle. Then it idles high for a few seconds before coming down, but if I twist the throttle the opposite way when it's idling high it moves the carb and the idle returns to normal. However, sometimes when I twist the throttle hard it just bogs. i took the plug out to check it and it looked dry, but not too white. So, whats going on? Forgot to mention that when I pulled the pilot screw out their was no o-rings on it. Is that normal?
