Compression Release not locking Question

[Nomad2day]

On my compression releases I have a difference. I can press the rear jug in and you can hear and feel it click down. On the front jug, when I press it down it pops back up and does not lock open. When I press the start button, I can feel it go down for a second. What would make it not lock down open when I press it?
I am concerned it is putting a strain on my battery and starter as well. The battery is 2 years old and I am getting ready to replace it anyway cause I am concerned it is not turning the motor over quick enough before the compression releases close and strain down on the starter.
Where can you get the socket to remove them also...
Thanks as always,
Neil

could be carbon build up.

i have the socket. could send it to you.

As long as you are talking the stock CR they will not "lock". With the factory EHC they will open for one second after you press the start button. This gets you past the initial compression stroke and should be enough to get the bike fired up. Both front and rear work the same way.

I was going to say the same thing the one thats locking sounds like the problem.Both mine will come right back up if I push them in manually.

Marv,
Thanks for the offer but I will just buy one. I will use it more than once if I know me...

Night Train,
I knew the EHC fired them for a second to roll through the compression stroke but did not know they should not lock open when pressed. Make sense though if they are a spring returned solenoid.

Alhall,
Any thoughts why it may be or seems to be locking open when I press the rear one. The next time I fire it up, I will put my finger on the rear one and see if it pulls down.
Love this forum, makes you change your thought process or what is really functioning properly or is not...

I wouldn't of thought it was sticking open once the motor is running because you would probably notice something is wrong due to the lack of compression in that cylinder

Thanks Lee,
Not really what I meant to convey. I mean I wonder why it seems to lock down when I push it in by hand when the motor is not running and not popping back up when I release it like the front. I am going to pull the tank and check both connectors to start with and ohm each one just to see what I get from front to rear compression release. Bike runs fine so I have to believe it is closed all the time but the rear one seems to lock down if I push it before cranking. I do not feel it pull down when I hit the start button. I had a starter jack-shaft shear in half so I am checking out the starting circuit.
They both ohm the same but the rear compression release is not pulling down when I hit the start button. At the pigtail for the two releases to connect too on the main harness, I tried the front one on both pigtails to ensure both had power and ground and it worked in either connector. When I plug the rear one in, it does not fire down. I am going to get a socket to pull it out and check everything and test it out.

I called S&S today to ask a few questions about the releases. It would help tremendously if they would listen to you before telling you things that have nothing to do with you. I wanted to know what the coils should ohm at which they could not tell me and offered this tidbit of advice...Punch a hole in the boot and spray some penetrating oil into it and that will loosen it up. I guess the water will not follow up later with a hole in the boot and she want get pregnant either....
I have ordered a compression release tool and will pull it and see what is happening on the bench in this case with voltage and see if the wiring has gotten in the way of the plunger somehow.
Pic to follow anyway when it all goes down...

Glad your doing all the research for us this year Neil but seriously I hope you can get some riding in soon.

Al,
I have been getting some riding in and played out at a rally last weekend. After talking to the tech at S&S yesterday and talking about how they can stick, I tried and successfully pulled the rubber boot off this evening and sprayed the shaft with some Kroil penetration oil I have. After letting it sit and pressing up and down some it quit sticking. That is good to see. I plugged it back up to power and hit the start and it fired down like you would expect it too. Too bad the battery was not up to wanting to play cause it died after 4 or 5 tries off and on hitting the start button. It usually is on the tender but the power to it has been off sense yesterday and it has nothing left. I guess I will pick up a battery at the Harley dealership in the next day or too. The battery is 2 years old. When the socket comes in I will pull it out and clean it up and put the rubber boot back on and take it for a spin.....
I also made a new exhaust bracket seeing how the other one kept breaking and had it powder coated black like everything else. Came out good...
