Hi everyone, I just jumped off of my DRZ400E onto the '07 400 XCW and I have a few questions. 1. I just learned that there are 2 oil filters, are they identical? 2. The bike seems to be running lean, anyone have suggestions for jetting? 85* - 95* Avg Temp/ Sea level - 500' Elevation I know JD is a good choice but it's pretty cookie cutter. I want to try to tune a little more specific to my environment. 3. Clutch disengages but seems to be dragging, is this normal? I appreciate the help....Thanks!!!
