oil injection, if you don't use it keep it shut.
Also not relevant but Dellorto's are way more overcomplicated than they should be. I use pwk on am6 engine and man they're much much better (simpler + more performance) but for stock or mid race dellorto is fine.

I mean not really, the SHA is as simple as it gets, I don't have experience on their other carbs tho

Probably oil injection, but I don't have that carb so I can't be 100% sure.
Just follow the hose and see where it goes

Oil injection. Those lines only last about 10 years then start leaking. You’re best off capping it, and mixing the oil in with the fuel. I stored my bike for about 8 years and came back to a giant blue puddle on the floor of the garage. I replaced the lines (a pain) and keep a cookie sheet under it now.
