'09 KTM 400XCW - Which Main Jet

Recommended Posts

This bike runs great everywhere except from 2/3 throttle on up. Seems to "blubber", hesitate, and stop accelerating. I'm assuming this is a main jet problem. Have a JD Jetting Kit installed which took the main from the stock 180 to a 178 and now a 175. Red needle in 5th clip. New plug, clean air filter and carb, petcock flows good, either ignition mode. Has FMF 4.1 w/power bomb.

Thoughts? What are others running with a similar setup? Thanks in advance.

Most likly its still rich from the accelerator pump squirt which continues for 3 seconds after you twist. So to accuratly judge jetting you have to hold the throttle steady for maybe 5 seconds so it can clean up the excees of the pump.

JD combo is well sorted for jets/needle taper etc so now you need to deal with the pump
