Accessories

Exhausts

R1

Some R1 exhausts are a direct swap. Others require adaptation.

Michael Ireton says:

I have installed the R1 cannister on my 94 GTS. IN order to do this you must

do four things:

1)Purchase 2 exhaust pipe reducer bushings, a 2 1/2 od x 2 1/4 id and a 2 1/4 od x 2 id. These will reduce the R1 canister pipe inlet to match the cat outlet on the GTS.

2)Drill out the rivets from the original strap location and slide it down and around to match the GTS mounting hole.

3)I used a flat round bar and a hammer to indent the R1 inlet pipe where the GTS rear brake lever interferes with the

pipe.

Consumables

Tires

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.

Spark Plugs

NGK

From the NGK parts finder:

  • Standard p/n DPR8EA-9, stock no. 4929, gap 0.035"
  • Iridium p/n DPR8EIX-9, stock no. 2202, gap 0.035"

Maintenance

Valve Adjustments

Clearance

Intake

.11 - .20mm

Exhaust

.21 - .30mm

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.
