Question about 1997 Suzuki GSF 1200 Bandit S
When a engine is cold the revs should be higher ( choke on ) but nit going up and down. If you release the accelerator and the engine still rev's up maybe the accelerator cables are not properly installed on the carbs. Also a air leak is possible. Check the cables and air leaks at manifold including the holes from manifold where vacuum gauges should insert when carb calibration is necessary. Those holes should have some caps on.

sounds like the main jets are partly pluged, you must remve all brass jets and seats including needle jet and its slide soak in carb cleaner and blow out with compressed air only.. hold up to bright light to verify if all are clean. jim

You have an air leak on the intake side of the motor. Get new carb and carb manifold gaskets. Tighten the bolts down evenly in three stages. For the exhaust, try the link below. It is a high temp silicone sealer.

i had a similar problem on a suzuki gs250t custom, my bike would not start some times and if did start, would run erratically, and cut out, this was after i changed the spark plugs, found out that the supplier gave me the incorrect graded plugs.

You need to fix the fueling first - without fuel it won't run!
Your other problem sounds like an air leak - either the manifold or the carb. Check by spraying WD-40 or CRC at the manifold and carb join while the bike is running - if the revs change (either up or down) you have a leak.
