I have a '00 mxz 700 sb w/DPM,I bought the sled wrecked last summer and pieced it back together,it seems to have a thick base gasket(actually i think it has 2) so I'm assuming the head has been worked to get comp.back up.It has v-force 2 reeds and looks to be mildly ported(trail ported) I also believe at one time it had pipes on it,due to all the heat reflective tape all over everything.It has been clutched,I dont remember what it had for ramps ,but it had a blue primary spring,and I 'm pretty sure it has a straight 50 helix. I gutted the airbox and put a bender can on the stock pipe,I jetted it to 380 & 390 and raised the needles 1 notch(as per Benoits advice)(they said this setup sounded like it came from the crankshop).This was too rich (fouling plugs) so I dropped ther needles back to center notch,and it took care of the plug fouling.I wanted to run the sled rich,because when I bought it it didnt run,and I dont know where the sled came from,so I just wanted to be safe. BUT,I know the sled is too rich by the trail of brown smoke it leaves when I hammer on it.(plus my plugs are quite black and carbony) Does anyone know what jetting setup works best for this application.should I go back to stock jetting?will the DPM compensate for the mods? I know I'm loosing lots of power,I want to get it back without toasting my buns. I live in central Vt. not sure of altitude,any help would be great!!
