Help identifying jets/jet kit

[bleeble]

How can I tell if I have a Dynojet kit installed in my carbs? Are there any markings on the parts? I ask because when I bought the bike the PO said he rejetted the carbs but fouled the plugs once (presumably because it was running too rich). Based on my blue headers and a sad attempt at plug chops, I think it's running too lean. So I'm guessing he didn't use a kit and just put the (wrong?) jets in himself. I'd prefer not to damage or destroy the engine by running too lean, so any help you can offer is appreciated.

I'm beginning to wonder if I bit off more than I can chew by buying an older bike...

The main jets have a small head on them and the needle is pointy. I do believe the DJ jets have a DJ marking. Plus the slides will be drilled through the hole next to where the needle comes out of the slide.
If you want me to I can take a pic of a mikuni jet and a DJ jet side by side.

A picture would be great. I still don't know my way around these carbs at all.

The smaller jet is the DJ jet. The needle is stock. The DJ needle is pointed with notches in it to raise and lower the needle.

Thanks for the pictures. Tomorrow is supposed to be a rainy day, so I'll have to open up one of my carbs and see what I've got in there.

DJ needles will have 5 slots on them, stockers one.
