Has anyone used the 6% advance timing wheel and torque loop.

Will it improve milage.

Will it harm engine.

Your throughts?

A couple of questions:

1. What bike are you talking about (GL1000, GL1100, GL1200 or GL1500)?

2. Are you really talking about the 6 degree pulse rotor or the 4 degree pulse rotor?

The reason I ask is folks usually installed the 4 degree pulse rotor on the older year GL1500's (particularly 1988 and 1989) and the 6 degree pulse rotor on the Valkyrie's

The 1988 and 1989 Gold Wing's had an "off idle" hesitation from the factory. Installing a 4 degree pulse rotor increased the timing and helped to mask the problem.

This problem was correct in the 1990 year bikes, Honda made some carburetor and timing changes that resolved the problems.

We installed a 4 degree pulse rotor on my friends 1989 Gold Wing Trike. It did improve the "off idle" hesitation somewhat and made the engine a little more responsive at lower RPM's but there was no noticeable difference in fuel mileage. This change did not require use of a higher octane fuel.

Speaking of the torque loop, are you talking about the torque exhaust pipes that replaces the exhaust chamber? If so, we replaced one of those on a friends 1995 Gold Wing, it was quite loud to his liking and he eventually removed it. As I recall, he did not feel the slight increase in performance was a good trade-off for all the additional noise.

However, your results may differ.

We've had other members try the advance wheel and as mentioned above it really doesn't do much good for 1990 and later 1500s. Of course this is all subjective so some say yes and some say no. That alone would indicate to me that the gain if any is pretty marginal. Same thing with the Extractor or Torq-Master, not enough gain for the money.

Thanks for the input. It`s a 89 and was thinking of the economy more so than power I`m planning on using this one for a comuter. 106 miles a day round trip for work.

If you are thinking of installing an aftermarket trigger wheel as a 'repair' you will most likely not be happy with the results.

As a matter of fact, MY experience with a 4 degree wheel was less fuel mileage, the need to run mort expensive gas, and a NASTY flat spot in the lower RPM range. I can't imagine what the 6-er would have done.

I just read all the inputs and noticed this is a 3 year old thread.
Your little input so far doesn't line up a whole lot as "the hard starting and poor mileage" could be other reasons you have not clued us in on, IE; it could be from leaking vacuum lines.

What year is your bike and more thoughts, input from you as to why you are thinking this route is your fix?
What are you getting for mileage and for how long a period of checking, averaging are you talking of?

FYI, the goldwing, (all years) have 2* built into to ECM. That is why there are two different advance wheels available. I would go with the 4 degree wheel for your scoot. 2*+ a 6* wheel & you will have pinging problems what ever gasoline you put in the tank, IMHO....-Rich
