Do Dellorto or Mikuni jets fit?

[AnotherWebUser]

I am going to order a couple jets for my bike, I ordered ones for motorised bikes but they are m4 not m5 thread, and I can't find any m5 ones specifically for motorised bikes, so I was wondering if m5 jets for a dellorto or mikuni will fit?

The engine is just a cheap chinese 80cc with the stock carb.

I bought these on eBay and they fit my stock carb. Beware the are all unmarked as to size.

Yeah those look very similar to the ones I ordered, but they were m4 and I need m5 jets, there is one set I found for motorised bikes that claims to be 5mm although the photos are the same as the rest, but they only have a 65 size and up, also delivery is about 2 to 3 weeks vs dellorto ones will come in 3 or 4 days. Has anyone used dellorto jets In their carb before just so I know that it works before buying a 3rd set that doesn't fit lol. I also ordered dellorto ones before but accidentally got 6mm ones.
