Leaking carburators
I found both my carburators leaking at the idle screw when I opened the fuel cock .
What could be wrong ?

Re: Leaking carburators
1) They will always leak if you leave the petcock on, especially on the side stand.
2) I always turn the petcock off and let it run for a 1 minute at every stop, even for coffee. Just remember to turn it back on when you get back.
3) On occasion I have used a very light rubbing compound to seat the needle. Don't overdo it, just a little.
4) On the side stand they tend to leak, as you said, try the center stand.

Re: Leaking carburators
1 extend stand and lean the bike
2 shut off petcock
3 shut off light
4 get off bike
5 take a moment
6 pull the key.
99% chance the carb won't over flow through the mixture screw.
On a cold start when on the side stand I hold down the right primer button longer than the left.

Edit just noticed you said both carbs were leaking.
