1150 carbs fit on an 850?

[psyguy]

my diaphragms have some imperfections, like if you would rub the rubber surface with a sand paper, not rips or tears, just little thinner material in a few places
not ideal, but i dont think it affects performance

i'd be worried only if everything else was perfect yet the bike boggs down mid-throttle

as the space above the diaphragm is constantly under the vacuum from the engine i think you would need an actual see-through holes and rips before the diaphragms could no longer properly raise the slides/needles
just a theory though
