Allan Zahrt with his Million Mile GL1000!

Honda GL1000 / GL1100 / GL1200 Head Gasket Details

Head gaskets on early ‘Wings are ultra reliable. The vast majority of these bikes are still running flawlessly on the original, factory-installed head gaskets which are now 30+ years old. Rare failures are usually caused by inattention and poor maintenance to the cooling system. But, a simple case of overheating can ruin your head gaskets. Warped heads are also a possibly outcome of overheating!

Recommended Honda GL1000 Timing Belt Change Interval

My recommendation for Honda GL1000 timing belts is simple: It you can’t verify their age – change them! Thereafter, my recommendation is to change them every 5 years or 25,000 miles…whichever comes sooner. Obviously, they should be inspected from time to time for any evidence of damage or deterioration which would warrant immediate replacement.

Starter Woes

Starter Problems

 Vintage Hondas like early GoldWings and CBXs have fairly robust starters. They do have wear issues that can lead to sluggish starting…especially when the engine is very hot. More on that issue later. A weak starter can cause hard starting…even if the bike is perfectly tuned. More on hard starting here.
