Surging...

[Wfreysr]

I have faintly noticed when cruzing down the highway at speed ( anywhere between 50-75) I would feel the bike slightly surging. However there is no notice of RPM change, just can slightly feel it. At first I thought it was wind buffet in but know that is not the case. Yesterday at 65 I really felt it a lot stronger than before.
I have a 2011 RTL SE5 with 31000k on it.
I have recently replaced :
iridium plugs and wires
the 2 vacumn lines (cracked)
New fuel filter
new air filter
purge valve (was sticking open)

Many thoughts or ideas?

Maybe with everything you changed the ECM is a little confused because of trying to run the engine as it was before. I would disconnect the battery for a while to reset the ECM & let it relearn with the new parts. Good luck.

.... You may want to start it and let it idle for 15 minutes without touching the throttle ....... Mike

Many thoughts or ideas?[/QUOTEWas your cruise control in use? I've noticed similar circumstances at times, but I think it's the cruise control compensating for changes in the road. I don't feel that it's a problem, though.

How did you make out?? All fixed up?

Sorry took so long to post back but I just had a chance today to do everything had a big skit schedule over the last week. I reset the nanny by disconnecting the battery left it run for 15 minutes afterwords also changed out and put another new fuel filter in and out no luck I still have the surging.
My question now with 31,000 miles on the bike a 2011 RT my thought the fuel pump may possibly be going?
has anybody had to replace their fuel pump out there at 31,000 miles or less or somewhere around there? What does anybody think? I'm planning on going on 150 mile ride tomorrow and we'll see how it goes.
