Honda CBR1100XX (97-07)

Front Suspension Upgrade Kit

2x Springs

2x New Length Tubes

2x Oil Seals

1x Motul 10W Fork Oil

Fitting Instructions

I rarely change the oil unless it looks emulsified so first off without:

Get a jack under the belly of the bike.

Undo the fork top caps.

Undo the damper rod ( 14mm nut ) from the top cap.

Do both sides

Get mate to lift up wheel and it will push up the whole of the insides of the legs.

Reach in with a digit and pull out the spacer.

Using a bit of bent wire ( coat hanger ? ) reach in and pull up the big washer on top of the spring.

Again with the hook reach in and pull up and out the spring SLOWLY AND CAREFULLY, else you will cover the bike and yourself in fork oil!

Once all out, keep the legs fully compressed, drop the new springs in, and top up the oil to the correct level  ( 154mm to the top of the tube for carbs bikes and 142mm for the EFI types ) 

I use a tube with a cable tie round it at the specified level.

Put the tube into the fork leg and suck ! When it gets to the right level you start sucking air :-)

Once that is done, drop the washer and the new spacer in, and refit the top cap to the damper rod.. Refit top cap to tube and job done.

With oil change:

As above but before you do anything else.

Get a jack under the belly of the bike so you can get the front wheel out.

Look up inside the fork leg bottoms and you will see a cap head bolt.

With a drip tray underneath, undo the bolts..

Undo the top caps and pull ! .. that will pull the whole of the damper assembly up... And the oil should come out the bottom.

At this point you might as well pull the damper right out and give it a good clean..

Once all the oil has drained out refit the damper and put the bolt in the bottom.. You may find it worth while putting the old springs and spacers back in and screwing the top cap back down to help tighten the bolt in the bottom of the leg. 

When you top the oil back up ( as described above ) pump

Then continue as above to complete the rebuild.
