Bike 1996 YZ125
Saturday I went trail riding and there were a bunch of long downhill sections of trail where I had the throttle closed or barely open. This caused my bike to LOAD up REALLY bad. I even ended up fouling a plug. I know my bike is jetted well up top and runs cleanly there but I have never been able to get the bottom clean. To date I have gone one size leaner on the slow jet (also called the pilot I think) and turned my air screw out 1 1/2 turns. If I'm on an open MX track 1/2 to full, the bike will NEVER foul a plug and always runs clean (Maxima SuperM 32:1). I am happy with the oil and ratio and want to stay with that. Does anybody have any other ideas to help clean up the bottom? What different jets should I change??? :think:
