Just bought a 1993 kdx 200. I know VERY LITTLE about these bikes, since I have been riding Honda XR 200 for last few years. My 15 year old son has "taken over" the Honda and I thought it might be cool to go back to my 2-stroke roots (late 70's Yamahas). Anyway, I like the bike so far but I have lots of questions. First, what's the deal with the "upside down" front forks?? Are the newer models like this too? Also, the guy I bought this bike from said you have to pre-mix your fuel and oil. I thought these bikes had automatic oil mixing? He said use 32:1 mix ratio. Is this about right?? Also, everyone raves about how much low-end these bikes are supposed to have. However, I am not feeling this. The bike is super-quick mid-range and top end, but bogs down too easy at low rpm. Could it be the FMF aftermarket pipe causing this or maybe a malfunctioning KIPS valve? Or maybe I have gotten too used to four-strokes riding the Honda. ANy help would be greatly appreciated.
