Could be applicable to modified suspensions too.

 

Different chassis setup

For better handling

Downsides

   

Raising the rear

Loss of rear grip

Lowering the front

Loss of rear grip and braking instability

More rear preload

Loss of grip on medium lean

Less front preload

Braking instability

Lowering fork oil level

Braking instability

Decreasing wheelbase

Loss of grip + Wobbly handling

Decreasing rake

Loss of front grip

less rear rebound + More front comp.

Pumping motion in curves

More rear preload + Less front preload

Loss of grip on max lean

 

For more rear grip

Downsides

   

Lowering rear

Loss of handling

Using all the rear shock travel (-5mm)

Squatting rear shock/Loss of handling

Raising the front

Loss of handling

heavier front springs/more preload

Loss of handling

Decreasing wheelbase

Loss of grip + Wobbly handling

 

For more ON BRAKES stability Downsides

Raising the front

Loss of handling

Lowering the rear

Loss of handling

More front fork compression

Loss of handling

Changing fork oil level

Loss of handling

Softening the rear

Loss of handling

Increasing rake

Loss of handling

Increasing wheelbase

Loss of handling

Less front compression

Loss of handling

More front trail

Loss of handling

 

Running wide Downsides

More comp. and  Rear preload Loss of grip

Decreasing wheelbase

Straight line instability/ Loss of grip more brutal

Lowering front preload and rebound

On brakes instability

Raising the rear

Loss of grip/On brakes instability

 

Bottom line:

 

Front fork

Harsh front end (over bumps) Chatter while on the brakes (gone when letting go of the brakes)
   
Lower rebound damping Reduce front preload
Lower compression damping Springs are too soft
  Rear ride height is to high: reduce reide height or spring preload
 
Small part of fork travel used  
  Front wheel jumps finishing braking
Oil level is to high: reduce  
  Lower the oil level if too much stroke remain unused
Change springs if its bottoming out
Front end feels unpredictable in brake/throttle transition  
   
Dial more rebound damping Loss of grip out of the corners
Dial less rebound damping if it feels harsh too  
Dial less compression damping if it still feel harsh too Lightly increase rebound damping
  Lightly reduce preload
  Rear shock spring is too soft
  Too high front end: lower the front
