Mixture adjustment?

[Maxedout]

Hi all,
Dumb question but Google failed me on this one.
Where are the mixture adjustments on my carbs?
Thx in advance.

They're labelled with the pink #2. You may have to drill out the tamper plugs.

Thank you for your quick reponse and picture but I have one question and am a bit confused?
Why would you have to drill to gain access to something thats needed?

I think Yamaha wanted to make it tamper proof due to emissions.

Thanks for the help again
Anything I should know before drilling?
Depth?
Drillbit Grade etc?

#8 drill bit should do fine. You should be very careful not to go too deep and impact the mixture screws. A depth gauge on a drill is the way to go. You should have to only drill about an 1/8" deep. Then use a pick to pull out the plugs.

I removed mine without using a drill at all. Get some #6 Phillips head screws with a nice point and carefully drive them into the holes about 1/4 inch (brass is soft). Pull on them with pliers and the plugs will come right out
