Both the owner's and shop manuals are available from http://www.YamahaPubs.com (Crestec Inc.). Only the shop manual is available from http://www.RepairManuals.com.

According to my recent interaction with the folks at ~RepairManuals.com, Yamaha has outsourced their printing to Crestec, which is the company being dealt with at ~YamahaPubs.com. The manuals I received from RepairManuals.com, printed in the USA (presumably, therefore, by Crestec), had very poor quality images. On the other hand, the owner's manual I ordered directly from YamahaPubs (a.k.a. Crestec) had a Genuine Yamaha wrapper and was of very high quality, an original print from the early 90's.

Accessories

• Tank Bags

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.

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...

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.

• David Sheldrake's ramblings on greasing the front suspension.
