Hoses leading to carbs on Bandit 600
Discussion
First of all I'd like to say thanks to the motorcycle community for being so patient and helpful with yours truly, the veritable motorcycle noob... just a couple of months in on my first bike, a bandit 600, and I have needed rather a lot of help from yourselves, reddit and anyone who's got a motorcycle who's number I have! Hopefully one day I'll be able to answer some little d
head with a crap bike's questions.
Anyway, my bandit's carbs need a clean but I need to wait till a friend with tools is free as everything is rusted and impossible take apart. I understand the need to dissasemble, clean and reassemble the carbs but in the mean time I have an airintake spray as a quick relief from my bikes symptoms.
My question is, looking at the carbs without taking off the fueltank, battery etc. there are a number of hoses coming off the top of them. two lead to the throttle, one leads to the fuel and one just kind of bends round and isn't connected to ANYTHING at the other end. I assume this is the air intake? So can I squirt my wynns air intake and carb cleaner in through that pipe whilst running the bike? And should that pipe be connected to something i.e the square air filter thing?

The two leading to the throttle are the throttle cables; they are what open and close the carbs when you twist the throttle.
The one leading to the fuel tap is, of course, the fuel pipe.
The last one is a breather hose that allows air into the float bowls to compensate for fuel flowing in and out of them; it needs to be open at the end to allow movement of air. Make sure the open end isn't too close to the intake of the air filter box or it can cause odd running.

Thanks for quick reply. So when Wynns instructions are squirt cleaner into air intake of carbs whilst revving I should squirt it into that? I just want to double check with someone that knows whats what before I do something very stupid.

No, don't spray it there; when they say air intake, they mean the air intake of the carbs themselves, i.e. where they join to the airbox.
On the bandit, you need to lift the tank off, take the four screws out of the airbox cover in front of the battery and take the cover and air filter out. Spray it into the open airbox.
However, any spray carb cleaner is little more than a waste of money unfortunately, snake-oil even.
Carbs get gummed up from being left with stale fuel in them or get dirt in them from rusty tanks. This then blocks the jets and passages in the carb itself so the air/fuel mix is off.
The only way to fix this properly is to take the carbs off, strip them down and clean all the bits and bobs properly; a spray cleaner will go nowhere near them.

Stupid mistake averted! So I take it it's not even possible anyway as the bike needs to be running when I spray the sThe only way to fix this properly is to take the carbs off, strip them down and clean all the bits and bobs properly; a spray cleaner will go nowhere near them.
t in the airintake but I need to take off the tank to do it?!MrSanti said:

Solution no.3 is to take the tank off and rig up an alternative fuel supply; extended fuel hose to a tank sitting on a worksurface or fairy liquid bottle strung from the roof, even a plastic funnel stuck in the fuel pipe and topped up from a kitchen jug full of fuel are all alternatives I have seen done before!
If you're doing the carbs properly, it is worthwhile doing the valves clearances at the same time and then balancing the carbs again afterwards; you will need a remote fuel supply to do this anyway.
