DRZ 400 E jetting for high altitude 5500'-9000'


Recommended Posts

Eddie, Just got a new to me KLX 400R with FCR 39 ,3x3 mod, foam filter, stock exhaust. just purchased it up in Denver. Now it is in Colorado Springs, Colorado. 5500' lowest elevation riding and up from there. Current jetting was apparently set up by you for an aftermarket pipe. It is currently set up like this

5500' - 9000'

Temps 80 deg low humidity

150 Main jet

48 Pilot

OCEMP needle on the 3rd clip from top

100 pilot air jet

200 Main air jet

65 starter jet and 2.25 turns out on the fuel screw

Coast enricher is removed

Does this sound right or is it rich? I think it is rich.

What elevation would it be safe to go down too with the 145 main and 45 pilot jet. If it would work at 6000' I may just put it in there and leave it. Or would a 148 /45 be better. Thanks, Eddie
