Suzuki GSX-S Fairing Removal
Fairings need to be removed first before removing tank cover, then immobilizer and then 2 10mm bolts to lift the tank. Its not a complicated procedure and with practice can take less that 10 minutes to remove all the fairings and lift the tank on the GSX-S1000F and even quicker on the GSX-S.
Best not to attempt in cold weather when the plastics are more brittle.
