Thanks to the members, I usually just surf this page when I need help but after a week of messing with my 97 magnum, and finding the solution here I figured I would share.
Quad starts and idles perfect, but started bogging at about 3/4 throttle 2 weeks ago. cleaned and adjusted carb, pulled air filter changed plug all the normal stuff. No difference.
Pulled off most of the plastics to get at the engine and check the cam lobes, and pulled airbox as well. before opening the valve cover I tried quad again for hell of it and low and behold it ran perfect, this was noted deep down in another thread. washed airbox out (no obstructions found) and put it back on (no filter no lid), quad bogged again, disconnected the snorkel to the carb and it ran fine put it back on it would bog at high rev. Nothing getting pinched, no rubber boots collapsing nothing blocking airflow, thought I was losing it.
Read one thread that said put it all back together and make sure no leaks, which I did, and greased all the mating surfaces, low and behold it runs perfect, still waiting for a new air filter but it runs with the old one better than without one at all. I still find it hard to believe the carb is that sensitive that a tiny airflow change but that was it. Im sure the carb clean plugs etc helped, but bottom line was the air induction system and aside from the filter and a little effort its a super cheap fix, considering the alternative (Cam, Clutch, carb, valves etc)
