Fuel screw trouble

[cnap504]

That does look like it and I have seen them online but the problem I have is they don’t have the XS1100 listed in the fitment chart. Also went to ronniesmicrofiche and they do not even show the part, I was thinking maybe because it was the first years of “plugged” idle fuel screws. Just wanted to cross reference the oem part number but can’t find it and as I mentioned the “fuel” screws I have found for Yamaha Mikuni BS 34’s reference several model but never the 1100

This is the 80-82 screw, the 78-79 is different.

Yes the idle mixture screw. Thanks

What are you calling a fuel screw? Do you want the idle mixture screw? A picture may help, the carb with location?

I have ruined one of my 1980 XS 1100 fuel screws and need a replacement. I’ve looked at online sources and what looks to be the correct part the fitment chart says otherwise.
Are all Mikuni BS34 fuel screws the same? And I can’t find the original part on a usually reliable microfiche source. Any help here would be appreciated
