4th gen carb tuning

96 VFR
Micron cut down slip on
K and N filter
unknown carb needles and jets
It's been de paired with proper covers

The plugs look a little too clean for my taste and it pops a little on decel

My question, can I raise the needles one position to get it a little richer?

Thanks

Are they stock needles and jets? If they're aftermarket needles, they should have different notches for the washers. Looking at my stock needles, you can add a thin washer or two under the head. Don't ask me how thin of a washer. That's beyond my knowledge. But my stock needles did have a very thin washer with them. Maybe 0.01" thick.

You shouldn't really need to richen up the jets, but going to 128s on the mains won't do too much harm.

popping is from the pair units.. pm sent

then you may have a leak in the exhaust flanges or a hole in the pipes..
