Hey guys, I am a new KLX300 owner. I recently purchased from a guy that didn't take care of it. The bike bogs down the second I pull fast on the throttle. Sometimes worse than others. It takes a second to get through it and once it does, it flies. I have done a lot to it in a weeks time. Cleaned the carb, adjusted the air screw, put new shims on valves, adjusted timing. Does anyone have any suggestions that don't cost an arm and a leg on how to eliminate this bogging?

Thanks in advance!
