The ones at the back of the tank have one bolt on each side under the seat, the front of the panel has a plasic peg which pushes into a rubber grommet. Pull the front outward about 5mm & slide the panel rearward
All the others are simply on bolts ....dont forget there is one under the "Triumph" badge
If your looking to remove the tank, the biggest problem is the front cross over fuel pipe..
Some days your the pigeon and others the statue
