Question about 2001 Suzuki VZ 800 Marauder
About ounce or twice aday when i engage my clutch and start to slow down my bike dies then will start up while in motion and run like nothing happened. yesterday while riding it began to spit and sputter like i had fouled aplug and died out then after sitting for 60 seconds started up and hs not had another problem. i recently had the carbs jeted and basicly rebuilt new floats etc any ideas?

SOURCE: Suspected problem with choke.
hey apparently and did are two different stories draining the float bowls and cleaning the carbs are two different things the fact that the choke dosent change suggest the carbs are stopped up after sitting for 1 year clean the carbs let them soak in carb cleaner and blow them out with high pressure air, keep notes of the adjustments befor you dissasemble them (air screws)

This sounds like an air leak is making the fuel/air mixture too lean. Any air leaks between the carb and the head will lean the mixture. Old, hard and cracked rubber manifold parts are the usual culprits. Old gaskets and "O" ring seals can leak air also. A bad head gasket seal happens at times also, as does an exhaust valve not fully seating. Air leaks are the idle speed problem.
A different problem is likely present in the carbs and that is what is causing the rich fuel smell. The carbs must be balanced. Example > If three of four carbs are perfectly balanced and one carb is not, then the 3 are "driving" the 4th carb. This will cause gas to spit into the air cleaner from the "bad" carb and can cause a backfire or two. Special vacuum gauges are needed to balance the carbs. Also be aware the carbs must be scycronizsed as well. The slides on all four carbs must lift at exactly the same time when the throttle is cracked.

When you are on the bike and riding do you still have the choke out? And stop spraying starter fluid into the carbs..bad bad bad.... bikes start with out that stuff and if you need it then something is wrong.. your gonna mess something up doing that....let me know about the choke and we will go from there...email@example.com

Please check your exhaust pipe or the silencer. It must have been chocked with carbon and you have to remove the carbon deposit to run your motorcycle.
Also clean your fuel tank as it could have dust deposits at the bottom chocking the fuel flow once it is in running condition.
Please change the spark plug as recommended after covering a distance specified.

Gas pouring out of the carbs means the float pin are not sealing in thus the over flow.
Go a little down thn .77in , best would be to bench set them.
Take a pipe say from the tank to the feed pipe of the carbs (best would be to remove the tank and place it higher on your work bench to get the gravity flow to the feed pipe of the carbs)
Allow the flow to the carbs and monitor the over flow, see which carbs over flow, remove the float bowl and reset the float and let it go a little less thn .77in, refit the bowl and retry the feed in and recheck..you will come to a point where gas wont over flow, open the bowl and see the level of the gas , it should be covering the jets, but remember that since you will have the float bowl out the gas will show low as when its submersed, the jet stem in the float bowl pushes the gas level up so dont get mixed up when you see the level low , i am sure you will be able to judge it for yourself.
I had the same problem in myYamaha(seca) XJ750R !981and finally managed to win over the problem going over it the way I explained.
Hope this helps! Good luck.
