My bike has recently started taking a lot of revolutions to start. O can't figure out where to go next. I took a video of it starting but there is a loud bird squeaking behind me. I have a fuel pressure tool to check when it warms up here in Florida. My only other thought was a coil going out. Once it starts it runs fine. Bike details are under the video.

2006 Dyna. 95ci with Andrews 37h cams. Decked heads with manual compression releases. Has had the updated injectors. 55k miles. Tuned professionally by Docs with TTS. Compression is even and good on each cylinder. No intake leak and it's not a loosened pushrod.

Battery does not drop below 11 volts when starting. Sits at 12.6 steady state and is charging fine.

I've changed the crank position sensor last week

Cleaned all sensors in the intake manifold. All sensors on the throttlebody are newer than the bike (I would say five years old)

 

Last time you changed spark plugs and or plug wires?

If OEM wires they are 20 years old.

 

Weak spark.

 

Did you check your temp sensor?

 

wires are stock type but not broken. Plugs are not fouled and about six months old. Oem

I have not. I did not even think of that

 

Fuel pump leak inside the tank?

 

I believe I can hear the check valve hose leaking inside the tank. Replace it, the filter and inspect the regulator housing while you're in there.

 

I forgot to mention this before. Original pump. I changed the in tank lines with gates submersible approximately 8 years ago. I also did the pressure regulator at that time

 

That is a known cause of slow starting. I would check the fuel pump and the hoses inside of the tank. I doubt that it is the ignition snce it runs well after a start.

 

While you're in the tank, check the routing of the hoses, some rub right up against the metal braces and rub holes in the hose. Reducing fuel pressure. Re-route away from the metal braces.
I did that about 10 years ago on my 07.
07 touring manual says replace filter at 25k miles, yours might be the same.
Found that out the hard way..............
