It's time to start putting the f3 back together and I'm an idiot and lost a gasket from the top of the carbs. I can't find them anywhere in any diagrams I'm looking at online. Are these not f3 carbs or something? I'm so confused

This is the diagrams I'm looking at.

You're looking for item #2 here. It comes as a kit, not sold separately. You get several things.

I had the same problem. You have to buy the whole rebuild kit and you need 4 of them. Honda dealer wanted $120.

 

BOOM buy these. Carbnuretor Airbox Sealing Rubbers Honda CBR600 F2 91-94 F3 95-98 Carb DBQ9 | eBay

 

Well.... I might have just screwed up with that ebay listing.

Description "Fits: All 91-94 Honda CBR600s. (F2 model). Removed from 1993 model."

Not sure if I can swear on these forums... Do these still fit?
