Title: Ignition advancer ready
Post by: Alf on May 25, 2017, 02:18:38 AM
More than 10 years I have kept in my wardrobe this Factory ignition advancer, waiting for to be used in a FJ 1100 or in my "new" 1200 1TX

It is no more available from Factory, I think

Probably be able to wheelie in second and third gear, after installing it. Good for another 15 horsepower@10,500 RPM.  :rofl:

A popular mod in the '80's I've had one on my '84 for years.
Vance and Hines and Factory Pro both made these advanced rotors.
First thing I noticed was a slight ping on long up hill grades (with stock jetting)
#40 pilots and Shimmed needles made that go away.

She seemed to start quicker, but that could have been from the coil relay mod.

Or you can do the ignition plate modification for free.

I recall not feeling any noticeable difference when I installed my V&H rotor.

Was that on your 85 or your 93?

Is there dyno from 3º/5º changed timing?
I am not into top end performace, but is there some noticeable gain in mid rev?
Title: Re: Ignition advancer ready
Post by: Alf on July 17, 2017, 02:08:08 PM
The gain is mainly at the midrange. In fact, increase the compression

Thx Alf,
you do have oil temp gauge?
Is there a big difference in temperature with ignition advancer?

I cant say if with the advancer the bike run hotter because my 3CV bike have fitted a bigger rad, and another improvements

And my 1TX is going to exit from the refurbish with a bigger rad too, so I cant get an specific verdict

Travelling side to side with a friend with another 3CV with oil temp gauge fitted too but with std cooler and with no mods, both bikes always were at similar operating temperatures

5 deg advance will make no difference to running temps. Retarded ignition causes hot running.

IMO
