I just got a chance to do some wide open runs with my slip-on. 1st and 2nd are awesome. Slight stumble in the beginning of 3rd for a second then pulls hard. 4th and 5th is way flat. Im runnin the DJ kit 144/146 clip in 3rd position and A/F screws 3 turns out with snorkel removed and K&N with proflow. Is this the pipe? Ive heard people say the WB pipe falls on its face after 3rd but this is crazy. Like I said 1st and 2nd are perfect and 3rd with a slight stumble for a second then cleans up. Im puzzled and wonder if other peoples are the same way or if I need to try something differant with my jetting. Im around 1000 ft above sea level. Any help would be great

I have an e-series w 14 disks, snuf-r-not endcap opened up, pro-flo no lid, DJ needles (custom location...different spacer set-up for my mild application), 165-167.5 mikuni mains, 10.75/1 JE, and a stage 1 hotcam.
The people that are not happy with the e-series have not taken the time too dial the set-up in perfectly for their particular Raptor..
KJMAXXX...I would richen the needles up a notch, test for the stumble..better or worse? Move the clip around until the stumble is gone...then go a little more (you can even add / remove thin washers for proper dial in) too check potentially more performance. Now more too the mains.....the mains are tricky on the Raptor because the Raptor likes a rich condition on the main. Go up on the mains until the engine shutters / balks, then back off one setting....test....back up another setting and test once again...better or worse? WHat does the plug say?
Baseline....take your lid off and toss it....leave your needles where they are (turbulence is introduced and you will be close in the 3rd slot) and raise the mains too 148-150 and test. Run some high quality filter oil....Maxima Fab 1 or PJ1 are good ones and protect the filter well.
