Rocker box issue...maybe

[2wheelmadman]

I removed the electric compression releases and installed manual ones, no problem.
Unfortunately after putting the rocker boxes back on i can't get the bike to fire up.
Lots of spark and gas, just won't fire up.
Is it possible the lifter rods are somehow affecting the valve positions? Any thoughts here? I didn't move the bike or do anything other than the releases.

So you removed everything down to the head? What engine do you have? I wasn’t aware that S&S had manual CR’s for their engines. I was thinking it was the electronic or a plug in the opening.

I used adapter fittings to a regular compression release, not an issue.

Check compression. If it has fuel & spark. Did you mark the push rods? If you put everything back in the same place it should be okay. How do the new releases work? Press them down? How do they reset?

 

[2wheelmadman]

Yes, just press them down and when the bike fires they seal up.
Mark the push rods? Not sure what you mean.

The pushrods are different lengths. Not a huge difference but the exhaust pushrods are longer than the intake. Possibly they are not in the correct position?

I thought I had them right but at my age ....

I know the feeling…I believe this is what Rottweiler was referring to. I always mark the front pushrod just so I don’t forget. Keep us posted!

check p ush rods and then let them leak down and spin test.

Good afternoon, I was thinking/wondering what did you do with the wiring that led from the original electric release valves? May be your issue?

Thats how we all learn!

Did you do a compression test? Quick and simple, before tearing it apart again. Even if the push rods got switched it would still show something. If there is no compression then the problem is with the new releases. I would think.

Hopefully you didn't switch the push rods. You could cause engine damage. If you were able to successfully adj the push rods you are probably OK. As suggested , a compression test is in order. Good Luck

It's called "Match Marking" makes it easier to put things back in the correct locations.

Ok, I'm going to blame this fiasco on my wife, apparently she backed the golf cart into my wheeled work table spilling the rods and various bolts all over. I am meticulous in laying out pieces in order so left rocker box and pushrods in order, you get the idea. When she picked them up she forgot to tell me and the parts all looked OK. Not so.
When I put the rods back in the longer one went on the exhaust side and shorter to the manifold side.
Fired it up, only running on one cylinder, no compression on the ther one Tore it apart again and swapped pushrods...voila! Like magic
Anyone know a good divorce lawyer .....just kidding!

 

[Rottweiler]

Glad it was that simple.

Still not real happy with the way the bike sounds, I'm thinking of replacing the pushrods with an adjustable set, but i can't seem to find a set for the 107, anyone have a supplier or a kit number? Tx guys.

Curtis @ Wildsteedworx can hook you up. Part# 93-5123 for S&S 107. You may want to pull the cam & lifters if you fired it off with the pushrods in the wrong place. Just a thought. Good luck!

Would be a good time for a cam upgrade

 

[2wheelmadman]

Yeah, you might be right Snuffy.
