More rough running and no answers
After reading volumes of complaints,issues and resolutions I cannot decipher my own 2007 DL1000 problems.
It was running fine over the winter then I allowed it to sit for several weeks in February without starting.
The weather went below 32F overnight and it was in a carport.
When I did start it ran quite rough at idle and all RPMs under acceleration.
A) Changed the spark plugs.
B) Slightly adjusted the TPS.
C) Synched and double synched the Throttle Bodies.
D) Checked the intake boots twice for poor seating. Fine.
E) Changed the Air Filter (With the gasket reseated properly).
F) Checked all vacuum lines for degradation or disconnects.
G) Ran with the fuel cap open.
H) Added Seafoam to the gas tank and burned a few gallons.
I) Pulled the Pump/filter out of the tank, inspected (fine) but did a filter bypass anyway for future preventative care.
And it still runs much rougher than normal with a heavy drop of power.
