So my 03 kx250 is bogging badly from 1/8 to around 1/2. I have gone from 42 pilot to 52 with same results (42,45,48,50,52) when holding throttle constant at 1/4 it just bogs itself down til it wants to die. Does this with every pilot I tried. In Montana, elevation is 3200 ft above sea level. I checked the reeds and they are fine. The reed boot is Sun cracked but not all the way through, when I pulled the boot I noticed there were 2 gaskets stacked on one another. I played with the needle a little but nothing. Mixing 32:1 on a 13 hour fresh top end. Any ideas?
