Hey Guys,

I recently finished the BK mod on my 01 YZ426F...


I did the best I could adjusting the timing and duration before it got dark and could not see. I road it around a bit and I feel like some changes in jetting are needed. At quick blips of the throttle when not moving the bike dies sometimes so I need to look into that. I also noticed that the pump squirt is pretty weak after setting the duration at around .35, is this normal?

Any ideas on jetting after this mod? My specs are as followed...

Location: Phx, AZ
Elevation: 1200 ft
Temp: 70 to 110
Humidity: >10%

Main: Dynojet 165
Pilot: 45
Leak Jet: Not Sure
Fuel Screw: 3 turns out
Needle: Dynojet needle 2nd Clip

Performance:
Dr.D Full Exhaust
UNI Filter

Any help would be awesome..Thanks!
