Remove Spoiler if mounted on the bike
Remove Hose clamp and mounting clamp from the old shock absorber canister.
Place a piece off masking tape on tail section and swing arm, and measure the ride height off the bike, note this down you need it later when you mount the new shock, so you have the same riding height.
Make sure the bike is secure so it is safe to take the weight off the rear shock absorber.
Use off a front wheel clamp and some strap downs is highly recommended to stabilize the bike. Use a hoist, jacks or mini lift ( see picture ) to lift the weight off the bike,
Unscrew the shock mounting nuts, and feel if the bolts are loose, otherwise lower or raise the jack/ hoist/ mini lift so the bolts are free off tension and can be pulled out.
By pulling out the bolts, the shock should fall down
Inspect the eye to eye length of the old shock absorber, and measure the Twin Motorcycles shock length, you can change the length +/-
Mount the Twin Motorcycles shock absorber, and put the bolts in and put the nuts on , don’t forget the washers and spoiler bracket if needed.

Tighten lock nut shock eye.
You can now twist the shock so it is clear off the exhaust and engine.
Leave the jack/ hoist / mini lift under the bike this will make the preload adjustment easier
Take the C-spanner and adjust the spring preload by turning adjustment ring so the bike ride height equals the measurement you have taken. ( adjust with the wide nut )
Length off the spring will need to be about 150 mm
After adjusting the pre load tighten the narrow adjustment ring to lock the adjustment
When adjusted remove jack/hoist / mini lift Twist the blue rebound adjuster so it is half way to 3/4 open ( 25 to 30 clicks from closed ) , and test the suspension, the bike should come up in a fast and controlled manner.
