Hi, Anonymous and the usual suspects are:
1. Fouled spark plugs.
2. Severely discharged or a damaged battery should have 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage the battery is faulty and must be replaced, AGM batteries fail in this scenario more so than lead-acid batteries.
3. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
4. Open-short-ground in the wiring between the alternator to the ignition module/CDI box to the ignition coil.
5. Faulty pins or sockets in the plug connectors.
6. Spark plug cables in bad condition, shorting/leaking, spark plug cable connections loose check for spark leakage in the dark.
7. Faulty ignition coil or electronic control module/CDI box.
8. Faulty pulse coil.
9. Faulty CKP, CMP, or BAS sensor.
10. Faulty ignition switch.
11. Faulty run/off switch
12. Tilt sensor needs a reset.
13. Security alarm failing to disarm needs reset

1 and 4 not gettin fuel or possible sparks ! check sparks first , if ok then remove carbs and clean jets etc !

1991 Suzuki GSX... | Answered on Mar 04, 2014


anything is possible given time and money, first is the space betwee the swing arm and the tire, then the tire size to rim, and then tire space to chain, talk to a speed shop

1991 Suzuki GSX... | Answered on Feb 06, 2011


remove farings, remove seat and gas tank

1991 Suzuki GSX... | Answered on Mar 08, 2010


Chain size should be a 530 link. Going smaller on the rear gives more speed, but less power!!! Going bigger on the front gives more speed also.
Keep in mind that one tooth bigger on the front sprocket is equal to 3.5 teeth smaller on the rear.

Buy the one htat fits-- duh!

1991 Suzuki GSX... | Answered on Jul 14, 2009


Just screw the cap onto the lead if it falls off cut about 6mm off the lead and try again, a standard socket for a plug of your size should fit be sure to use a proper plug socket
smoke from the front of the engine could be from the exhaust where they bolt to the head,
Get your self a good degreaser and wash down the engine then run up the bike and look for oil leak dont ride the bike as a little oil will go a long way and it will be harder to see where its leaking, usual suspects rocker cover gasket if the oil is high up,
