Series Regulator Source SH775

[posplayr]

Hey guys I am thinking about putting a compu-fire on my 1981 gs550T. I have been doing some looking and I am also thinking about rplacing the stator while I am at it. Does anyone have some good recommendations on a good stator. I am rebuilding this bike from the ground up and I am wanting to do it right.

Thanks,

andy

el
ectrosport stators seem to use heavy epoxy and have instituted product inprovements on potential fail areas.

Another vote for Motosport as the cheapest right now with shipping.

A used one will do

There are still a gazillion used ones on ebay for $45. In fact when I looked I saw one for $36 shipped so I bought it. The "New" ones for $60-80 are fake, but the used ones have the polaris part number on them. I even hooked one up backwards (switched the connectors) and it survived.

Hi All,

It appears prices for the SH775 (PN4012941) have doubled recently. If you are considering one, I have found only three shops who have it at reasonable cost.

Partzilla: $78.38
Bike Bandit: $78.35
Motosport: $81.24

Everywhere else is $140 to $170!

At that price get the Compufire. More efficient(less heat), less current draw when off and smaller

Placebo effect.

Not possible because I'm just recording the numbers but maybe it's luck or weather.

We know you are in denial.

One thing I noticed with the new setup.. my mpg has gone up about 10%. Now some of this is related to warmer temps but I am getting mpg numbers which I've never seen before. My last tank was 57 mpg. I'm 90% confident that mpg has gone up 5%. My riding is "little old lady" and mostly highway.

Interesting this is the first time I've seen anybody report higher MPG using a series R/R, although it has been long suspected that the extra stator heat represents power loss. A smaller bike and very docile driving is what would show this the most.

I went with an SH775 for the GS550L a few weeks ago. I swapped stator at the same time with a Caltric.

The previous setup was a El Cheapo Ebay stator and a Honda 5-wire RR. The Honda RR seemed to work ok but the stator blew out after 2k miles. Not sure if the RR was the cause but anyway...

So far I have 500 miles on the new stator and SH775. I built a nice little harness for it using bullet connectors and the kit you can buy on-line.

The new setup also seems to put out a bit less voltage and drops off at low rpm. At cruise I am getting 14.3 but at idle it can drop down to 12.7. Probably ok and could be due to fewer widings in the new stator or because the SH775 is a little less efficient.

In any case I am please with it so far. It fit right into the space left by the Honda stator. Tight fit but it worked.

Any shops in Europe / Austria / Vienna to get this SH775 — trying to buy local instead of going with Amazon / eBay

You can look up local Polaris dealers through their website.

I have done so for Switzerland, but after one to two phone chats, I went the amazon route instead.

I think what he means is that Polaris must think their R/Rs are failing since they sell so many of them. Triumph must wonder about their connectors as well.

At least some people in Polaris and Triumph are well aware of why sales of their respective components have gone through the roof. All we can hope is no bean-counter seeks to cash in on it...
