Flooding Issues on Vintage Hondas

Flooding is a common problem in vintage Hondas – especially on bikes that don’t get run much.  Flooding can be just a minor aggravation …like hard starting or poor fuel mileage. But, it can also lead to catastrophic problems such as severe engine damage or even a fire!  Flooding issues should not be ignored!

Low Power Issues on Honda GL1000?

(This Tech Tip is written for the Honda GL1000 …mostly applicable to any vintage motorcycle.)  

If you’ve ever ridden a “healthy” GL1000 you will agree that it is a surprisingly fast bike …especially given its vintage. The original design goal by Honda was slanted toward “sport” rather than “touring.”  In fact, when GL1000s were new in 1975 – only the mighty Kawasaki Z1 was faster.  Honda was shy about publishing actual horsepower figures, but the design goal was 80 horsepower at the crank. That’s quite respectable …even today.

“Insensitive” Idle Mixture Fuel Screws?

I often field this common complaint: 

“I’ve noticed that turning the idle mixture screws nets different results on each of the individual carbs on my Honda GL1000:

  • #1 will kill the motor if turned all the way in
  • #3 has NO EFFECT on engine speed regardless of where it is set
  • #2 has what might be considered a “normal” effect
  • #4 has only a very slight effect if any at all

What does this mean????? I’m a bit confused?  Help please!!!!”
