Randakk's Amazing Honda GL1000 Timing Degree Wheel

- for both Static and Dynamic Timing

A Randakk Excusive!

Timing a GL1000 is considered by some to be a bit of a black art. It's actually pretty straightforward once you have done it a few times. The ignition system on GL1000's is inherently marginal. It's imperative to get the ignition spot on for best performance.

Now, through the miracle of higher math and close supervision, Randakk's has forced our minions to pack a full 720 degrees into the space normally occupied by a mere 360 degrees.

Through extensive field testing, We've found that the use of this special timing wheel:

  • Simplifies the timing process for both static and dynamic methods
  • Eliminates some of the mysteries of wasted spark ignition
  • Reduces errors: a full 720 degrees and all timing events are marked on the wheel
  • Improves accuracy
  • Eliminates the need to drain oil and use the special Honda viewing port tool for dynamic timing

Even the most careful static timing seems to be about 1-2 degrees advanced compared to dynamic timing. It is very hard to stop at the exact instant that the timing light goes on (or off depending on how the test light is hooked up).

Dynamic testing is beneficial because it reveals problems like weak advancer springs, "sticky" advancers, etc. which only show when the engine is running.

Also, the "split" timing anomaly when checking both F event's on a given coil/points pair can be visualized nicely when dynamically timing. In a perfect world, the two "F" marks on the disk should superimpose and appear as one using a strobe, but they will actually appear to cycle back and forth slightly due to the anomaly. This effect is due to slight errors/slop in the eccentric and "wobble" on the poorly supported rear end of the left cam.

Each Timing Degree Wheel Features:

  • Made on heavy gauge 1/8" aluminum stock
  • High quality, stain-resistant graphic appliqu??
  • Complete with 7+ pages of color instructions
  • Complete with required attach hardware: bolt, washer, star washer and spacer

Works with both breaker points and electronic ignitions such as the exceptional Dynatek Dyna-S.

Special thanks to Steve Seamans ("Whiskerfish" at NGW) for invaluable assistance on the R&D for this product.

Two different versions of this Timing Degree Wheel are offered for the GL1000.
