Love it!!! Best outside the box thinking yet!

Just finished up the install on the compufire on my 1150, cleaned up a lot of connections along the way, it is now charging SUPER STEADY, 14volts at idle and never gets above 14.5, according to the new digital volt meter I installed. I did notice an improved idle which seems bit strange unless the fried regulator was just not allowing the proper voltage at idle, I hadn't checked it in many years.
If all else said about the compufire units is true they are worth every penny. Although the unit is a bit large, if I was still running a air box I would have had to find a good spot to mount it.

The SH-775 is larger than the Compufire and if you put the connector on the SH-775 it is even bigger still.

As for using it as a bobble on a chain, the Compufire is a but more refined look, where the SH775 has more of a bling factor.

I hang mine from a gold chain around my neck for the bling impact.

A big attention getter from women I'm sure.

Along with the foil hat from the attack on Texas thread you'd be the coolest kid in class.

...if I was still running a air box I would have had to find a good spot to mount it.

I mounted mine up front right above the oil cooler since I still have the stock airbox, and I am sure there is voltage drop due to the longer wires, but I used the provided 10 gauge wires so hopefully not as much.

just some further info, I need more info to verify this but my oil temps in my 1150 with the new compufire showed a decrease.
my gauge doesn't work so I use a fairly cheap laser temp reader. In the past after a ride it would read 190 to 195 at the sight window. Checked it today at the sight window 178.

Assuming that site glass area is reflecting oil temperature pretty well, that sounds about right. You can read about other people also reporting drops in temperature. It is not just the Compufire on 16V, but at least one other guy has noticed a drop in an 8V using a SH-775. The 1100 and larger motors are the most noticeable.

Just purchased a Compufire R/R and an Electrosport stator per Jim's advice. Going to install them along with a Dyna 2000 ignition this coming week.

I just did the same.

Good products, great ideas, well-advised by smart people. GSR= Grand Support Resource

If I have a problem with a Stator, and or regulator, I will probably go with a Compufire. I might possibly upgrade the fleet if that happens.

I don't know why anyone would purchase a Compufire R/R in this day and age when a SH775 series type R/R is available for much cheaper while still being a high quality unit.

One thing I can tell you guys also is that using a series R/R will not noticeably reduce oil temperature in your engine. I'm repeating myself again here but the only way for an R/R to affect oil temp is if a large amount of current is shunted back to the stator to the point where the stator is heating up way HOTTER than that of the oil. A GS will run oil temps well over 200F and I do not believe shunting current will spike the stator temp above this level. In order for the stator to heat up the oil it would have to get this hot all the time. Another thing is that there is very little oil inside the stator cavity; the only oil in that part of the engine has to go through a small hole in the engine cases. So even if the stator was baking like an electrical heater and running above 250F or so there isn't enough oil coming in contact with this hot device such that the entire quantity of oil in the crankcase plus all the mass of the engine is heated above the normal engine temp. Nope, ain't gonna happen.

Not to mention I performed an oil temp test on my GS1000 and ran both a SH775 and a shunt R/R for 30 miles each, back to back, and there was NO difference in measured oil temp. Period. End of story.

There are very good reasons for purchasing a Compufire as well as why the oil temperature drops.

The Compufire R/R's are an excellent product. An YOU Jim were the primary driving influence which got everyone around here onboard with purchasing series type R/R's. My only point was that since the SH775 has hit wide spread release, AND IS CHEAPER than a Compufire, purchasing one has become the defacto standard these days.

The primary reason to buy a Compufire is it is much easier to fit and will fit in the stock location of a GS1100EZ/ED. You claimed you know of know reason.

 

[mnferwerda]

Fit was the main reason I bought a Compufire over the SH775. I managed to squeeze it in the same place as the other one. With the SH775, I would have had to relocate it someplace else.

You can then find satisfaction in the knowledge it also provides:

• a slightly higher low RPM voltage (0.2V) and
• dissipates less power; probably (about 5 watts) and
• has zero drain current compared to about 2 mAmp for the SH775.

I installed the Cycle Electric 601 on my 1000G. I voted 2000 miles.

 

[Guest]

I will use the Compu-Fire again if I ever build another bike that needs the conversion. Smaller size is the motivation for me over the SH-775

 

[850 Combat]

I don't like that the Shindengen SH775 has a big plug on it. It doesn't come with the connecting plug and pigtail, does it?

I go to trouble to minimize the number of connectors, due to eventual resistance and heat. The Compufire looks like I could just solder the pigtail.
