83 Gl1100 project bike

Post by Steve_S »



Bought a not quite basket case 83 GL1100 to muck around with. Allegedly just needs the carbs rebuilt and the rear master cylinder rebuilt. Looking forward to getting my hands dirty.

It needs timing belts. That's Job 1.

Timing belts are the booby trap in the Goldwing engines before the 1800 (which uses chains).

The Wing has an "interference" engine, meaning that the pistons and valves take up some of the same space, so they MUST be properly timed to keep from hitting each other and breaking your engine.

If you don't have paperwork showing that they have been replaced in the last two years, AND the bike has been regularly ridden, you're in the danger zone -- if the bike has been sitting, they can take a set and break just by turning over the engine. If one fails at highway speed, expect to buy a new engine.

They cost about $20 each (you need two, buy Gates belts) and will take you an hour or so to change on an 1100. There are videos and posts with pics showing how.
