Len_Anderson Posted July 13, 2005 Burned, First my DRZ 440K Before the 440 I had: Main 160, PJ 38, PAJ 5/8, EMM 3rd, main air 200, fuel screw 1 1/2 turns. This was with Yosh cams, Wiesco 13:5 and PCT4, ran crisp and strong. 500ft to 6000ft. Now with MT440 13:5 seems rich all over using a 152 main and the above settings. Down on the main? Suggestions or a starting point. Next a DRZ 400E 500ft to 6000FT Hot Cams IN & EX, FMF Q, stock piston, Advanced jetting: Main 158, PJ 38, PAJ 5/8, EMM 3rd, main air 200. With the fuel screw turned all the way in it continues to idle with PAJ at 5/8. Should I continue to back out the PAJ to 3/4 or more or change the pilot jet?

Wayward Son Posted July 13, 2005 First my DRZ 440K Before the 440 I had: Main 160, PJ 38, PAJ 5/8, EMM 3rd, main air 200, fuel screw 1 1/2 turns.

Suggestions or a starting point. with the stock motor and EMM needle 160 was pretty rich.155 is good for a stock motor.with modified motor i wouldnt be suprised if you were 145-148. Next a DRZ 400E 500ft to 6000FT Hot Cams IN & EX, FMF Q, stock piston, Advanced jetting: Main 158, PJ 38, PAJ 5/8, EMM 3rd, main air 200. With the fuel screw turned all the way in it continues to idle with PAJ at 5/8. Should I continue to back out the PAJ to 3/4 or more or change the pilot jet? opent he pas to 3/4 and retest.the bike may still idle but the idle shoudl at least deteorate with the fuel screw full in. i would drop the main jet on that motor to a 152.
