Need a new STARTER BUTTON
« on: October 14, 2013, 01:00:04 PM »
Hi,
recently acquired a K75S, 1987.  The little green rubber cover is mostly gone on my starter button.  I believe it is what keeps the button up, so consequently my brick will try to run the starter at times I am not expecting :(   Anybody got a spare one they'd want to sell me?

Look up starter brushes and load shed relay. They give those symptoms. The button is pretty cut and dry. if it springs back up Id be more worried about the other problems.

Sounds like your battery voltage may be too low, if you are not operating with at least 10 volts on the battery the starter relay has a tendency to weld closed and then the starter remains engaged.  That's why some BMW riders get more than a little obsessed with battery replacement every 3yrs.

Anyone have any luck finding a replacement starter button for these k bikes?  I've seen a few posts about attempts to 3D print these, a one-off brass button example, and finally a syringe cap that has seemed to work as a replacement, but haven't found any options for an OEM purchase.  The button on my bike has come apart leaving the center portion attached to the switchgear.  Gluing may be an option although that might be tenuous at best?   I can still start it but would prefer not to leave it this way and would like to avoid the cost of replacing the entire switchgear.  If this isn't an option, perhaps an alternative would be to remove the broken button piece and add a momentary push button starter switch somewhere on the bike???


Thx. :2thumbup:

Thanks Laitch, I would have never found this site on my own.  Just goes to show the value of this community and members like you.  :clap: BMW still sells the indicator buttons and some other replacement parts for the switchgear, but not the starter button for some reason.  :dunno Surprisingly, these parts seem to have been designed poorly from an ergonomic and durability standpoint (out in the elements, gloved hands, high use), but for 15 bucks shipped, which is kind of spendy for a tiny little green button, if it works I prefer this option to replacing the entire switchgear!  :2thumbup:

My K75 had the same issue, I guess old age made the plastic brittle. I put in a used K100 switch from eBay, it fits right in to the bars and the loom with no mods needed.

I used the Harbor Freight, "plastic welder" and some of the green PolyPropelene rod to add material to the top of the OEM button. Both to add to the superglue strength, and to build up the material a little. As a side benefit, it's pretty close to the same color of green!
