Poll for Compufire R/R Users

[tkent02]

I have never had a stator go bad, have bought a few bikes with bad stators already. All with corroded wiring. This new type regulator sounds like a no brainer anyway. Shutting off the power that isn't needed instead of wasting it as heat, brilliant. Going to buy three for now, probably more in the future if they work out well. I didn't realize there are a few different companies selling them, who has the best built regulator at the best price? Is there any difference functionally between the different brands? Thanks for all this information.

I have a new ElectroSport ESR090 (not Electrex) regulator on the GS650G now but might consider the Compufire if I have to do more work on the wiring. As far as I can tell, the stator is good but I don't like some of the wiring and still need to clean up grounds and remove bullet connectors before making a final decision.

My long departed GS550T did not have regulator problems but fried a stator at 15,000 km.

Fitted a compu-fire on my 1100 after the battery got boiled at Reno this year. So far so good, seems to be doing a good job. Can't tell if the stator is running cooler or not but hoping it is and I've seen the last of those burning up. Not sure how many miles yet but it's not that many so voted less than 500.

Since I found this discussion interesting, I took a look at CompuFires website and found that they have 9 Series regulators listed in their catalog. They all have various current specifications ranging from 22A to 38A. Which one would be the correct choice as a replacement for an '81 GS550L? Anyone care to hazzard a guess?

I'll be installing a Compufire on my GS1000E very soon. It just boiled the water out of my battery again. It takes about three months, but it is a regular occurrence. I need to add some heated glove liners to the mix, so it sounds like the Compufire might be the ticket.

can we make this a sticky?

I need to update my previous post. It seems that my GS650G fried a stator at 20,000 km and popped the regulator at 25,000 km. I missed a re/re comment on one of the service orders and the cover gasket in the list of parts installed. I recall blowing a fuse on the way home from work and charging the battery to ride to the shop the next morning.

So now my score is 50% on Suzuki regulators and 100% on Suzuki stators.

Those are failure rates right?

Did you vote in the poll for blown stators with OEM R/R?

Yes, those are failure rates. Two bikes, one fried regulator, two fried stators.

I voted on the blown stator poll.

I plan to give my Compufire a hefty workout this year. Painting and polishing is the only scheduled down time.

I vote on the compufire. I have the CE-602 right now. Works great. 13.8 V when the revs are up. Does not get hot. Fits nicely under my battery box. I have a GS1100G. The OEM rectifier sucked. Replaced 4 stators and 4 rectifiers.

Wow that is a real biatch

I'm just curious about something. I have a set of Electrex RR and stator and at 1200 idle It climbs to 13.7 after a bit and shortly after 2000 it hits 14.4 and stays solid at that no mater what the rev's above that.

I just noticed that I see allot of people posting that they get 13-14 v only when reving and less at idle with the compufire.

How well will a compufire RR do against the Electrex ?

I'm in the "thinking about it"

On the typical GS's that I have seen they are a zero charging rate at about 1250-1350 RPM so the battery voltage will be right about 12.8-12.9V. Depending upon what R/R you have it can take about 1500 RPM to get 1 amp of charging current (e.g. 13V at the battery).

If you are at high 13V's at 1200 RPM I'm guessing the EL stator is wound differently to produce a higher voltage, but likely less current that the stock of Electro sport stators.

The charging voltage is also a function of the battery voltage. If the batter yis down the voltage will be lower.

Other than the stator winding (which effects voltage v.s .RPM characteristics) the R/R will effect the output voltage at low RPM. The FET type or Series type R/R's have FET's instead of bipolar switches/diodes so the internal drops are lower by about 0.5V (you only see this at low stator voltage output).
