Don't forget to change fuel filter!
I do most of the work on my bike (07 FXD) and have never really thought about the fuel filter as it is inside the tank. Well I decided to change it out and glad I did. I don't know how the bike kept running. The old filter was so clogged up you could not even get air through this thing! I have a little more than 30,000 miles on the bike but will be changing the fuel filter more often for sure. Just thought some of you might be interested.

First sign of a FI Harley with a fuel filter being stopped up is it will have trouble idling since it affects the necessary pressure and the IAC valve will not be able to keep up. The fuel pump actual pumps in excess and has a bleed valve in the tank system which some people mistake for a broken line. Since most modern gas pumps have filters it's just my opinion but I would not worry about it unless you have a need to go into tank. May not be on the really new Harleys but my 04 maintains same pressure for all rpm ranges. Idle will be first to go
