you can rebuild your leaky petcock, but often that won't fix it. just replace it with a Pingel or Drag Specialties petcock and be done with it.
wipe out your airbox.
change your oil and filter.

R4 stated: "Even with the fuel setting on PRI (prime), none of the carbs should flood if the floats are set and functioning properly and if the float needles aren't worn and/or needle seats clogged."
I have to disagree here... The float assembly on any vintage bike or new one, for that matter is NOT intended to be a gas shut off valve... it is intended to be used to METER gas during operation. This is why ALL motorcycles sold have a petcock that either has an OFF position to manually shut off gas supply when the bike isn't being operated OR has a vacuum petcock to shut off gas automatically when a bike isn't being operated.
ANY bike will leak if the carbs remain supplied with gas and the bike is parked, especially when the bike is on side stand. The downhill (#1) carb is almost always the culprit. TURN YOUR GAS OFF or MAKE SURE YOUR VACUUM PETCOCK WORKS or install an inline gas shut off valve if you don't want carburetors to leak when the bike is parked. Think about WHY the added complication of a vacuum petcock was put into most bikes in the 80s... the manufacturers knew that carbs leak if gas isn't shut off and the vacuum petcock is an attempt to fool-proof turning gas off.

Wg said it best, dont think its a carb issue think its a petcock issue. My honda has a vacuum petcock, but upon replacing the gas tank I mangled the filter that pushes up into the tank on the petcock and left it out. Leaked gas if parked on the sidestand ever since. My bike does have an off position tho as well, and simply shutting it off stops the gas from leaking. That filter is like 28$ by the way, ill stick to shutting it off.
