Cleaning the carbs on a 1992 Suzuki Bandit?

Can I just spray some carb cleaner in the carbs to clean them or do they need to be completly taken apart, and also is it my carbs. The bike will run with the choke on, but when I tke the choke off it shuts off any ideas?|||Sounds like one or more clogged pilot jets. A tech will charge you about $300 to strip and clean them, but what he may actually do is fill the float bowls with a mixture of Yamaha carb cleaner and fresh gasoline and let it sit overnight. Then he will start the bike up on the mixture, or on fresh gas, and if he is lucky, your jets will be clear and he can charge you the 300 bucks for about 45 minutes of work.





You could risk 10 bucks on a bottle of Yamaha carb cleaner and try it yourself. This is not a spray product. You can use a pump oiler to inject the mix through the fuel lines. Unless your jets are really, really gummed up, the vapors will dissolve enough varnish to clear them. Chase it with half a can of SeaFoam in the gas tank to get them really clean.





This is really simple compared to removing a whole bank of carbs, and works often enough to make it quite worthwhile. You will feel really smart about having $300 to spend on a pair of tires.|||runs with the choke on because the jets are clogged and its starving for fuel,so yes they need to come off the bike and be cleaned properly.|||Sounds like you might have a clogged idle jet. Spraying carb cleaner into them wont clean them. You need to remove them, disassemble them, clean the floatbowls, inspect the needles, clean all the jets,you can use a tiny piece of stripped wire to run through a clogged jet to get gunk out and spray cleaner through every circut in the body. If a rebuild kit is in order, now's the time to think about it. It sounds like a lot, but in real time, its only a couple of hours work, and time well spent once its done. Cleaning the jets is very important too...if debris gets stuck in them it screws everything up.
