Hi, Timothy_towd "ABSOLUTELY" you need to go through all 4 carbs set the proper float height and then have them synced for this scenario you will need your service/owners manual if you can't find the first and best tool you ever bought for your Yamaha, despair not, for a mere zero $0 you can download another one.

I have a 1991 Suzuki GSX600f (Katana), it has been stood for a while and will not start, it has a spark but very weak on all 4 plugs, I have changed the cdi unit but it is still the same, engine cranks as...

If the motorcycle has been dormant for a while the I would fully suspect the fuel system is clogged with sediment. Gas over a period of time even as little as three months under the right condition can produce this foul smelling gas ans basically shut the gas off from getting to the carbs or injectors or if yhou hav gas to the card then the jets are plugged.

No amount of trying it going to make it run and if it does start then it will not run properly.

Unfortunately the fix is to get the fuels system trained cleaned and serviced.

You are not alone with this problem

It can be worked around with what is called a fuel stabilizer added to the gas before long periods of storage.

So for the bad news

My suzuki ozark, 2001, won't idle, pops and snaps after it warms up, and the exhaust manifold turns cherry red up by the head. i have to hold the throttle to keep it running, choke on or off. I cleaned...

well the cherry red exhaust tells me that its getting way too much fuel, and the idle problem will continue if the float inside the carb is bad, or the needle for fuel cut off is stuck, either way the carb has to come off to be thouroghly cleaned, and check the float, it should be fverry light, and if its a brass one, shake it back and forth by your ear to listen for fuel in it, this will make the float sink lower in the carb and not allow the fuel to shut off. good luck hope this helps

Does it smell rich like gas isn't being burnt and coming out the tail pipe? If so then it's probably the spark plugs. Actually I bet you any money it is. They're cheap and easy to replace, give it a try.

My Suzuki Intruder 750 of 1985 is not running smooth and is giving fuel from the first cilinder exhaust , my best guess is the choke which is may be stuck , what do you think ?

It could be a stuck choke, but it could be a stuck carb float, or needle valve. You may want to pull the carb bowl off and check and clean.
Once you get the bowl off, you can use a can of spray carb cleaner to spray the needle valve (gas inlet to carb), and inside the bowl, any jets and around the choke. Also check your air cleaner.
While you're at it, pull the spark plugs, and check to see how they look. I would clean them with carb cleaner, make sure there's clean metal at the electrode and replace any that look questionable.

Hi i've got a gsx600f the problem it won't rev up it will idel on full choke but soon as i start turning the choke off it dies i have cleaned the carbs and put in new plugs the bike was stood for a while

The main metering jets in the carbs,can get clogged and usually can only be cleaned with a small drill bit, or in some cases if you have someone that uses syringes for insulin, they usually are the right size. anyway these can be a big problem, but if you can blow through them, then they probably are ok. The other thing that can go wrong with setting too long is build up in the bottom of the gas tank expecially if you have a reserve tank...they are much harder to clean...if the new fuel filter that you put on keeps getting clogged, this is a good sign that you still have debrie somewhere in the fuel system. Also, you want to make sure that you have a good setting on your float level, and I like to put in new jets when they have set for a while, you can loosen the drain screws on the carbs individually and see if there is anyone of them that isn't bleeding the same to give you an idea whether the floats or needles are doing their job...hope this helps.
