I have a simlar set up but am running the full FMF, will be the MRD soon. I have the 150 main installed at sea level. But it is not 100% right. Will the 150 jet cause the bike to bog down of the line and have a lot of decel popping? It will also cut off if you quickly twist the throttle to more than half way at idle.

The 150mj won't be causing your bogging..have you done o ring mod ?..

Popping on decel is normal...Try turning your fuel screw out 1/8 th turn to help calm the pop..

Your jetting will be the same for ssw/mrd pipe..

What needle setting are you running?....

[getting_nuked]

Yes, I have the o-ring mod and the EMN needle.

[Craigo]

Did you turn your ap timing screw in 1/2 turn

[getting_nuked]

No, I did not mess with it. Is that accessible with out removing the carb?

[Craigo]

Yes.It's the screw with the green paint....http://i775.photobucket.com/albums/yy33/CraigoDRZ400sm/FCRO-Ring3.jpg?t=1302429145

[getting_nuked]

Ok I will try that tomorrow. I see to turn the screw in, is there a starting point to set the timing screw before the adjustment?

[Craigo]

Untouched..??..You are at the starting point...Take note of any adjustments you perform..so you know where to go back to if required...

[getting_nuked]

Sorry for the delayed response. I adjusted the AP timing screw and completely fixed the bogging down at takeoff and initial throttle. I have a tiny bit of surging at about 1/16 to 1/8 throttle. I will probably change out the slow air jet and add the 160 main to try to cut down on the decel popping. Craigo, thanks a lot for all the useful info.

We seem to have had a win....Good news...?
