Check the condition of the petcock (Valve) in the tank, open it up off of the bike. does fuel run out freely? if not take it out of the tank and service it , some have screens to trap debris. these can gum up wth debris and varnish from old gas.

Hope this is of some help.

I have a 1991 suzuki bandit 400cc, i cant get fuel down to the carbs, i have had the tank cleaned, installed a new petcock and had the carbs cleaned, also put all new fuel lines on it, still n fuel, im...

Have you pulled the line from the petcock and checked for fuel when you turn it to on or reserve?
If you have fuel flow then maybe the floats are stuck blocking the fuel from filling the bowls. Tap on the float bowls with the handle of a screwdriver. Also if your carbs have a drain screw on the bowls open them and see if fuel starts to flow.
I don't recall if your bike has one, but I have seen few carbed bikes with electric fuel pumps as well. If yours has one then that is for sure something to check into.

You may find the petrol filter is blocked. That is usually at the top of the petrol tap in the tank. Unscrewing the petrol tap will reveal it.
I always recomend the manufacturers parts as they have more expertise than us!
Fit original carburettors, they were designed for the engine after all.

Carb would be the place to start assuming it was running fine before it was stored. Gas can "varnish" in carbs while in storage for long periods of time if a fuel stabilizer wasn't added before storing. Might try some fuel system cleaner before going to the trouble of removing the carb.

The bike will not take throttle, refuses actually, carbs are clean and in sync, Bike idles perfectly, but when any throttle is given, the engine is restricted to 2k rpms. Stock jetting, and a slip on pipe.

i think the fuel filter inside the tank is dirty, or the fuel on the float bowl of the carb is low that when you give gas the fuel in the bowl runs out.

How do you change the choke cable on a gsf 400 bandit

Once you remove the gas tank, it will be very obvious. Cable easily comes out of the thumb mechanism easily when you take it apart.

I ride for about an hour then it dies. it acts like a fuel problem. it will start back up but will die when i give it gas. if i wait about ten minutes, it starts up and rides finee

possibly **** in your tank which has blocked your jets in the carb, clean out tank and fit an in-line fuel filter and clean carbs, imports often did this due to rust inside tank, if its bad take off tank and put in an old bike chain with some oil and shake the **** out of it, flush it out and drop an old speaker magnet inside tank to colect any rust in the future then fill it back up with fuel

Wont keep running

Maybe some water in an electrical plug. Remove the tank and dry it all out with compressed air or WD40. Work around the coils and other wiring. Also where the wires come out of the engine case.
