Fuel Filter

The OEM fuel filter is expensive and will probably be out of stock at a dealer. Alternatives are:

  • Purolator F44661
  • AC/Delco GF708
  • Fram G6495

According to Bob Taylor, any fuel filter that fits a Mitsubishi Starion (87-89) (Australian) should work.

Feeler Gauges

The Genesis 20-valve head requires feeler gauges which are narrower than most. Some people cut down standard gauges, but there is concern that this will leave burrs.

Shim Substitutions

This ST1100 page lists bikes with shims interchangeable with the ST1100. Presumably the relationship works both ways...

ABS

Front Suspension Lubrication

The dreaded front-end squeak. If you hear the squeak, the bearings in the front swingarm should be disassembled and lubed as soon as possible. If this isn't done in a timely manner, the bearings will eat themselves and are quite costly to replace.
