Technical: what are these thingies for?

Just curious... why is there a little bolt on each downpipe?

I have them on my ATV and they are for draining water out of the exhaust if you go through deep water. I have one on the header and muffler. Why they are on my Triumph I have not a clue. Sorry

They are for using a gas analyser when adjusting mixture - insert probe here.

Be very careful with those!!!! They hold the exhaust bearings in place, and if you loosen them the exhaust bearings will fall out. It's incredibly hard to find new exhaust bearings for these bikes, and they can only be used once.

Just kidding. :razz: It's what Chris said, that's where you plug in the EGA probes for tuning purposes. :-D

Cheers,

Exhaust bearing!? I thought they said muffler bearings. I'm sure I have relative bearing maintenance due at 12k. Will the same lube work for these or what. :-g :-g :-g :-g :-g

Thanks for the replies, so THAT's what they're for... for the exhaust gas analyser. Of course.

um, what's an exhaust gas analyser? :razz:

"um, what's an exhaust gas analyser?"

-It's a fancy name for a form of suicide. :wink:
