my bike is going to be out service for a while and i was wondering to save my self the hassle of cleaning the carbs later if i can drain them of fuel now?
 
Should be screws on the bottom of the bowls.

Should be screws on the bottom of the bowls.

If you have a repair manual or owners manual you can find more info on storage preping. Like putting oil in the cylinders and several other things. Cleaning the carbs is going to be needed sooner or later. Yamaha makes a product that can be mixed with gas, ran through the fuel line into the carbs, and drained out before runing the bike. I have not tried it yet, but it seems like a good thing to keep the carbs clean without tearing them down.
 
I've canvassed a bunch of pros on this question and I haven't seen any consensus. All agree that the bike should be stored with a full tank of fresh fuel treated with fuel stabilizer (available at any autoparts store), and that the engine should be run for 5 or 10 minutes to ensure the treated fuel reaches the carbs. Where they differ is whether to then drain the carbs. Some say drain, others say top up the carb bowls by opening the petcock for a few seconds every couple of weeks so as to avoid gaskets and O-rings drying out. I've been leaving the bowls full these past three winters without apparent problems. Who else can weigh in on this?
 
We don't have this problem in Calif. The purpose of storing with a full tank of fuel is to keep the tank from rusting. Depending on carb there is usually a bolt/screw in the float bowl that can be taken off to drain the carbs. personally with the use of fuel stabiler I would keep fuel in the carbs, (check them once a month) so as to not dry out the gaskets/O rings. I would also put in fresh fuel when it is time to ride again
 
I keep a full gas tank with STABIL mixed with the gas, and drain the carbs when I store it. Has worked on my non-rebuilt carbs for 20+ years. Thay are clean as can be.
