GL1100 carbs... slider cap orientation

Post by OldguyGlen »



Bike is getting ready for road tests as soon as the snow drift melts off the patio so I can get it out of the basement.
But while doing final reviews, and tinkering with small details, I come up with one more question.
When reassembling the carb rack, I mounted the caps (top of the carb, covering the vacuum sliders) with the "K" logo outboard. I now notice my originals pics (pre-disassembly) show these caps with the "K" inboard. They seem to fit in either orientation. I don't think they actually have sliding contact with the sliders (pistons) themselves. So, are they OK, or do I need to reverse them. Bike starts and runs great during my stationary testing. Revs up nice, idles down nice. But I'm still nervous about them on backwards. Any opinions from the experts??? Thanks.

on both my wings i have the "keihin" mounted outboard. several road rides with wing1 and a few round-the-block test rides with wing2 revealed no running issues whatsoever.

Thanks Jo, You gave me some confidence.
I think there is only an air gap at the OD. The piston slides on the center post ID, and I think it might rub in the bore in the carb body. The piston only assembles one way (square groove up one side). Maybe it is a good thing to rotate the cap (which would rotate the center post as well) to "even out" the wear pattern. There is some side-thrust on the piston from air pressure, as it slides up/dn. That side thrust must exert some wear on the friction surfaces. I guess I'll leave the "K" logos outboard unless someone else gives a better explanation.

Doesn't matter really but I always put them where the Keihin logo is right side up looking at it from the outside.
