From the factory they are capped with a pushed in brass plug.
You can and probably should adjust it. They were set very lean and capped at the factory for emissions. If the caps have not been removed already, not too difficult to drill/pop them out. You will want to remove the screws plus spring washer and O-rings in order to clean this circuit. First, before removing, gently turn the screws clockwise by half turns, counting as you go. Stop as you feel resistance as tightening them completely will damage the tips and their ability to meter mixture accurately. This will give you a baseline setting. When reassembling, return screws to baseline and then adjust. Clockwise to lean. Counterclockwise to richen. Have fun.So I can't adjust it?

I am guessing as my bike is older, but perhaps 1.5 full turns out from lightly seated. A guru will correct meHow many turns out is the default, I'm thinking 10 half turns.
Yeah, I have the chock fully out, then when I can rev it I go halfway with the chock then when I start riding it, I push the choke all the way inYou need a richer mix when the engine is cold, that's what the choke is for. If it's doing this with the choke on then maybe the chokes aren't working, or working fully. Maybe the choke feed jets in the float bowls are plugged or partially plugged. Here's how to check them .....
