Slam button

[ShawnD]

Just rebuilt my starter solenoid on my 08 k9 and while I had it all apart I added a slam button. Bike turns over and starts great with handlebar start button and the slam button but when I push the slam button the starter stays engaged until I hit the start button on the handlebar. Any thoughts as to why that's happening?

Sounds like you may have got it adjusted to tight

When you double check your adjustment make sure you have no binds in the button and also that your springs are not broken and operate freely. It sounds like its sticking in mechanically and when you hit the start button it just happens to release it.

I just had another thought. When you are satisfied with the adjustment and operation of the Button be sure to lock tight the jam nut and adj screw. If over time it loosens you could loose the plunger .

I didn't realize there was any adjustment needed but now that u say that I do remember there being a flat head screw bolt on end of plunger, is that what your referring to?

Loosen starter bolts but still somewhat tight? Thinking the motor will torque it and square it up somewhat better. Just a tap at the motor should line it up. Remember, you're sort of finding the happy place so as not having the shaft cocked.

OR... since you can physically push the shaft in via button, remove main fuse or battery ground cable, have a loose starter motor, push the button in, where [I think] this moves the gear into the flywheel. The motor's body moved to the happy spot; tighten the motor bolts, release button. The shaft should follow back... is now square to the flywheel.

The adjustment is on the slam button itself. It has an adj allen screw with a lock nut at the end of the plunger. It's so you can a adj the throw on the button.

The screw needs to be close enough to the plunger to make it have good contact when you push it in but not so close it can arc when at rest. You kind of have to feel the adjustment because you can't see it once you put the button back in place. Approx 21/2 to 3 threads showing above the Lock Nut.

I read my post again and saw that it may not be very clear. Here are a couple of pics that can help. I really meant the end of the button. Not to be confused with the solenoid plunger which the button pushes in.

Thanks man I'm gonna get into it tomorrow and see if I can fix it thanks for all the info and pics I'll give yall an update after.

Well tore everything apart and tried both ideas loosened starter bolts pushed slam button several times. Pulled off slam button assembly, there is no adjustment just a smooth shaft put it all back together same problem. I feel for some reason it's electrical but haven't changed anything as far as that goes. So just gonna let it ride I guess starter works fine. May regret it down the road but fuck it!

My pictures must be a different brand slam button. The pics were a Spyke Slam button.
Try This: Take the neg side of the battery off and push the slam button in. If it sticks you know its a mechanical issue. If there are no binds and the button springs back into position easily I would have to guess that some sort of back circuit is being created and supplying voltage to the solenoid and hence holding it in. Very weird I don't even know if what I just said is even possible on a starter. I have one in my garage I can look at to see if I have any clues. I will let you know.
I do believe you should figure it out or remove the slam button because the regret you speak of may be 150 miles down the road and of course if bad luck has it's way it will be the middle of the night and raining.

I agree. When you said you hit the start button again to kill the magnetic field, it causes the shaft to retract back. I've had the shaft kink on me on assembly, so I tried that trick and it worked for me. Thus the suggestion to get that out of the way. I would think the relay is locked to cause the motor to become magnetized like normal. Then hit the starter and it grounds or stops the flow to the relay?

Unless... but then again, you let go of the slam and it retracts by itself. Something sounds like it's reversed electrically. Is the relay still in the starting loop? I mean, to hit the start button and it stops, you'd think the relay is still in the loop... so is it? And if it is, pull the relay, start it and then see if this works like a normal slam. And say if it is still stuck, you again press the start button to stop the current flow... h/bar switch? What other wires [in the starting system] loop back to the wire(s) at the start button going in and coming out?

Sorry, A little late to the party...

Sounds electrical, since everything seems to be moving in the right direction I am guessing you have the stock EHC in the bike? Slam Button probably feeding an electrical loop back into the stock module which is why it's staying engaged.

Since the slam button is more of a "hope to never use it", if you ever need to use it just unplug your green solenoid wire to prevent that feedback loop.

BTW the one designed without an adjustment is the better one. Not sure why spyke made them adjustable the nut has loosened up on me before and the starter engaged riding down the road one day. Had to pull over and unplug the battery just to get the starter to stop spinning what a mess, and sure way to wear out a battery/starter quickly. Took the damn thing apart and that slam button came off as soon as I got home and replaced with one that isn't adjustable and already fitted with the correct height so it functions correctly on it's own without any way to get messed up.

The green wire that plugs into the left side of the starter assembly? I thought that was a compression release wire is that not correct?

That's your solenoid wire.. it's what triggers your starter to engage when you hit your start button. Sends +12v to the solenoid to throw it.

Nothing to do with the compression releases. Unless someone has modified the wiring...won't go down that road yet.

Just try it, see if you get the same result! Only a 5 second test. Just put it back when your done and then you can get back to riding it like hell! Then you'll know if you ever need to use the emergency button

That was it!! It fired off and disengaged. So say my starter button doesn't work down the road will I need to pull that wire to start bike or no?

Haha every once in a while even a squirrel finds a nut!

I would just keep it in the back of your mind. Obviously If you don't you'll probably get the same result so you'll remember quickly..lol.

Ultimately, yes it would be best to remove it just to prevent the feedback loop. If you kept doing it time and time again it could ultimately wear out that relay in the module. But don't get to worried about it hopefully you never even need it!

Good work around but I'm really curious how the back circuit was created. I've looked at one I have on the bench and just can't come up with a simple explanation for this to happen. Any Thoughts??

Thanks for the help guys I really appreciate it!!! One more mystery solved for someone else down the road also!
