Here goes! Probably the one-millonth to ask. 2004 KDX220 has developed (suddenly) a horrible rattle from what I think is top-side. I'm not ready to believe in my mind it's the lower end main crank bearing (been through that before). Rattle is bothersome, but overwhelming issue is the engine bog with little-to-now idle which eventually leads to complete chock-down and engine kill, terminating with significant back-fire out of pipe. Can't even ride, much less put in gear and take-off. Engine dies after about 3 minutes of idle and throttle manipulation just to keep running.
Any thoughts? Willing to take top-end off again to look around more. Power valve assembly?? Can study BikeBandit schematic long enough to completely remove and replace.
Want an expert to lead me in the right direction. Days ago changed piston rings, BUT problem was occuring before that!
