A heads up on harness connectors

[WJBertrand]

The other day when I arrived home I noticed a blue plasticy thing resting atop the transmission directly behind the right cylinder. I poked at it and retrieved it with a pair of long nose pliers. It was a blue rubbery thing I recognized as a seal from an electrical connector.

Oh oh, must’ve fallen out when I had the bike all apart doing the valve adjustment back in December.

As luck would have it, all the connectors accessible with the air cleaner box in place weren’t missing a gasket. Pulling the air box and opening each suspect connector, I eventually find the connector to the throttle body motor has no seal inside it.

I sure don’t want water getting in there and monkeying with the throttle! This connector is identical to the connectors to the coil sticks that all have the little blue gasket in them. I popped the little seal back where it belongs and buttoned her all back up. If I hadn’t seen it lying there on the transmission case I’d have had no idea it was missing.

So when working on your bike check to see that these little seals don’t fall out.

Yes, be meticulous when working on machinery. One must account for every single part fastener seal, the list goes on.
Also, be sure to count your tools.

Also keep plenty of dielectric grease on hand.

OH! You mean for the BIKE. That good advise too.

Similar find when I installed the MCCruise control on my 13. Bike was all back together, and working well after some quick diagnostics. Cleaning up the bike lift and found a very small yellow plasic locking clip that goes into an electrical connector to stop the terminals from backing out when you push the two halfs together.
Back in to find the connector with the missing clip.

Thanks for the finger print set for my next break in!

Of course this is standard practice, but in all my years of wrenching I've never had a seal like that fall out so it was not on my radar to check this. This experience includes changing the entire main wiring harness on an ABS ST1300! I didn't realize these seals weren't retained somehow and could even fall out like that. Unfortunately I didn't notice the part until literally months later, which makes me think it was hung up somewhere else initially, then fell down into view.

Just a small dab of diaelectric grease will help retain those seals in place and help seal the connector as well.
