71 CL350. Carbs have odd jets im not familiar with. Pushed in jets in bowl with a spring type holder the bowl presses against to hold in place, and a screw in type jet with a rubber plug. Wondering what sizes are stock for all three as my new kits had different mix screws than stock.

Where can i find jets for this and what is a good start others have been successful with? Is shimming the needles necessary on these carbs/bikes? Im not new to rejetting and plug chops, just not familiar with these carbs/jets.

It should be stamped on a flat spot on the side of the carb body.

Most pods don’t work with these carbs. There is a set of UNI and one or two from K&N that work min these carbs

all the little pods are terrible for these carbs. Stock sizes are 35, 105, 68

Yes 3D carbs are correct for your K3 bike.
your primary, secondary, pilot, float height and base idle mixture settings are the correct stock jets/settings. I use 68 for the primary above as it was stock for other years

I can make them work with K&N filters.
They can't be 'jetted' directly as you will have either a super rich or super lean condition around 4,000rpm or 7,000rpm
