What is the spark plug gap on my 89 gs500e?

Facetious answer:  "Hmmm, I don't know....  How about you measure it?"  :lol:

Helpful answer:  This section from the Haynes manual should tell you what you need to know.

Thanks for the info, this should help me get much better performance since I got the bike.

NOTE: The gap on the NGK site is expressed in inches.

That says 0.035 inches... which would be 0.889 mm.  I thought the stock plug gap was 0.7 to 0.8mm.  I've been running a bit over 0.8mm, and here I thought I was running wider-than-stock!

I thought the stock plug gap was 0.7 to 0.8mm.

See the Haynes link in my first post.  The stock gap is 0.8 to 0.9mm.

So you're fine.
