PARTS AND ADVICE FOR YOUR 'OLDEN GOLDIE'
An online source dedicated to Honda's amazing four cylinder Goldwings!
The GL1100 evolved from the GL1000 and although a very different bike there are many parts, mainly engine, that are interchangeable. There has been many queries as to what parts will fit which bike.
For those interested, here's a breakdown:
Compatible GL1000 and GL1100 engine parts.
Rear belt covers
Belt covers, gaskets and bolts
Rocker box covers, gaskets and bolts
Rockers, rocker shafts with springs
Valves, springs, keepers and caps (not '83)
Belt tensioners and tension springs
Cam wheels, retaining bolts and keys
Top water transfer pipes, thermo housing, thermo cover and elbows
Oil pressure sensor, temperature sensor, fan switch
Front transmission cover (80-81 with rear ignition unit, not 82-83)
Water pump cover
Pumps drive shaft
Main bearing shells
Most of the front shift mechanism
Neutral switch (80-81)
Cylinder heads (GL1100 left head needs to be modified for the points system)
Alternator shaft and damper, damper rubbers
Starter chain and sprockets
Starter motor (1100 to 1000, not 1000 to 1100)
Oil pump chain and sprocket
Clutch (1100 clutch in 1000 may need 1100 clutch cover.)
Primary chain tensioner ( 1000 oil shield needs modifying)
Primary chain slider block
All gaskets except cylinder heads
Most of the internals do not interchange
You will hear 1100 pistons can be fitted into 1000 bored out. Boring the 72mm to 75mm leaves the liner only 1.5mm thick, with not much alloy behind to support. Not recommended.
Parts interchange between GL1000 and GL1100
Compatible chassis parts:
Non-vented 1100 brake discs will fit 78-79 1000
80-81 1100 front brake calipers fit 78-79 1000
77 on 1000 headstock will take the triple tree from 1100 & 1200 (obviously that means the complete front end too)
Radiator grill and mounting covers with hardwear.
