New R75/5 Tuneup: Stange Bing Plug

Starting the resurrection process on the newly acquired 71 /5 and began with rebuilding the carbs when I found a stick, yes, a stick stuck in one of the ports. I know it didn't get there by itself so, I'm wondering why someone would plug it and should it be plugged?

Cheers,

Yes, it should be plugged. That's a vacuum takeoff port which comes in handy for carb syncing, but otherwise it should remain plugged. It should be threaded on the inside, so find the right size screw and loctite it in there so it doesn't back out. That's probably why there's a stick in it. Someone noticed in the middle of a ride that their bike wasn't running quite right and on further inspection heard it sucking air because the screw backed itself out with vibration. They probably just plugged it then and there with whatever they could find on the side of the road and forgot about it. Also, the little rubber vacuum caps work nicely there as well.

Ah, thanks for the quick info! I should have it ready to start in a week or so, still waiting for bits.

Cheers!

The screw is part # 13 11 1 259 869

The red fiber washer is part # 13 11 1 259 870

You may want to balance the carbs because a stick seldom will stay tight in the vacuum port. (yes, I know this from personal experience) They leak. The OEM set up is great. It works with out Locktight.
