What is the cheapest thing that I can put in there and be confident that it is going to work as well as OEM? I have noticed that OEM parts are rather expensive and "authentic" Mikuni jets are double the price of others. Is there a noticeable quality, performance, or reliability difference here or am I just throwing my money away for a name? I noticed that many of the kits do not have the float valve screen included in the picture. Do I need to find that separately? How often do the rubber diaphragms need to be replaced? Only when they break?
Basic carb kit: K&L 18-5064 - available on Amazon, Ebay, JP Cycles, etc, etc. This contains a new float needle, float seat, float seat o-ring, bowl gasket, and some funky little o-ring that I don't know what it does. Works well.
No, it does not come with that screen. You should be able to clean it. If you really need a new one, then OEM is the way to go.
The "rubber diaphragms". Not sure what you mean.
There is one on the slide and is part of the slide.
There is on in the TEV (Throttle Enrichment Valve AKA air cutoff valve.)
Both are a bit pricey. Only replace if failed.
