2001 YZ125 PC pipe FMF spark arrestor top end with about ~10 hours I had a lot of oil running down the back of my silencer after my last few rides. Temps in the 50s maybe low 60s elevation 1500-4000 ft. Was running: Main: 460 Pilot Jet: 22.5 Needle:#3 position Today i tried out the procedure in the jetting sticky to test the pilot jet. I could not get it to idle at all running what i listed above. So i changed the pilot jet to a #20. Now i can get it to idle. Temp about 75 about 200 elevation. The manual says: 59-77 F Main: 460 Pilot Jet: 25 Needle: #3 position 86+ F Main: 450 Pilot Jet: 25 Needle: #3 position So i am a little concerned about how lean i am on the pilot. But it seems like if i can ge it to idle pretty nicely can't be too off.
