07 dyna. All stock except exhaust. Started feeling it kinda pop and surge a bit to work the other day. Turned around and headed home and it got WAY worse. Can keep it running if I feather the throttle. Doesn't want pull off from a full stop. Backfiring out the throttle body. Changed plugs and wires. Checked internal fuel line, fuel pump still sounds strong. CPS tested with a magnet for voltage readout. Seems good.. idk where to go from here. Wanted to upload a video but apparently I cant..

Should also mention it smoothes out for a minute.. then goes back to it.. like it's surging

Check your battery connections. Check your air filter. Check your fuel system.Test your coil. Compression test.Leakdown test.

Does it get better if you let it cool off?

Nope. Does the same cold or hot. Got a CPS and TPS on order.

It only has 9000 miles on it so I wouldn't think compression problems as of yet but maybe!
Pulling the fuel system out today to take a look.

no codes?

 

[BrokeWinger]

Just get gas?

 

[Wiredog]

Why are you replacing parts that you don't know are bad?

Check it again......and the fuel filter while you're at it.

None

check intake seals at heads and carb/throttle body. Popping on decel is a sign of intake leak. When it is running spray spray some wd40 on intake seals and see if it runs better.

This sounds like the IAC is hanging up. Remove the AC and spray cleaner up into the pintle port until it runs clear and cycle the ignition several times while observing the IAC pintle movement.

I've also had this happen when the exhaust nuts loosen up after changing them out and not retorquing soon enough.

My 06 Dyna did that same thing…. It was Lose battery cable’s… wobbling lose.. fixed that and it ran like a top…

My carbureted Vtwin Honda did that a few years ago and the cause was leaking carburetor to cylinder boots. I tightened the boot clamps 1/2 turn and it straightened right out.

Make sure your battery ground is secure to frame and battery. Also check hot wire connections. I just had a situation where my Dyna ground to frame connector broke completely in half and was vibrating against each piece just enough to get the bike started and get home, popped surged ect.

Air fuel mixture is very important. What kind of pipes were added? I'm assuming the bike is EFI. If free flow pipes were added you may need to accommodate them with a free flow air filter.

Was wondering as it has been a few days, did you find out the source of the problem?
