charging system question

I have a 85 GS550L
I have read through the forums and could not find exactly same problem.
my battery is about 7 months old. A few months ago i replaced the R/R, I bought one from Z1. just recently I replaced my stator, bought one from electrosport. The bike runs, but it doesnt seem to be charging well. somewhere between 3500 & 4000 RPM its getting its best charge at about 13v. When I put it up to about 5000RPM it drops but stays between 12 and 13. The battery is only holding a charge at about 11.99 cold the next day on or off the bike.

my second question is... I have read alot about using a honda R/R or late model CBR R/R, the only thing im not sure of is what one would be the right one for my bike? meaning does it matter what year or just anyone?

I am a bit of a newb, but learning alot. mostly from this forum.
 
Hi,

Feel free to check my website for information that I've collected. There is electrical stuff in the "More Info/Odds and Ends" section.

Have you had a chance to clean every electrical connection and ground, from the headlight to the tailpipe? Corrosion causes resistance, the bane of charging systems. Run a dedicated ground wire from your r/r to the negative terminal of the battery. If your battery was not initialized properly it may have trouble holding a full charge. It wouldn't hurt to have it load tested again.

Mr. duaneage will sell you a tested, modified Honda r/r for a very reasonable price. Send him a PM. He stands behind his parts too. He's not like the junk sellers on ebay. There's also a list of compatible parts in another thread: CLICK HERE.


Thank you for your indulgence,

BassCliff

It sounds like a reasonably normal charging system to me. A bit low on volts but not too bad. Do you have a really good ground for the RR? Run it directly to the battery, that fixed a similar problem with my bike.
It also sounds like your battery could be on it's way out... do you have a charger? Put in on charge until it's full & then check it. You should get about 12.3v & it should hold that for at least 2 or 3 days.

I an hook you up with a Honda RR kit wired for your bike. Plug and ride for 40 bucks delivered.

Send me a PM if interested

I've seen those Electrojunk R/Rs not work out of the box.

+1 !!!!!!!!!

My brand new "Electrojunk" (I like this term) was OVERCHARGING since new to the tune of 16.2V !!!!!!!

They told me to go pound sand as far as a warranty replacement. Electrix/Electrosport SUCK BALLS as far as I am concerned as a company. I later added a Rick's unit, and all is good now.....
 
Thanks for all the advice:)
I think I will have the battery load tested again due to it only holding a charge of 11.99.

I checked the wiring, no Corrosion and the R/R has a ground to the battery.

***I got the bike for $900. It had 1 prior owner and it has only 6500 original miles. it was in his garage, last time it was driven was 1994. to get it running I rebuilt the carbs and had a friend of mine who rebuilds old bikes adjust them for me. has zero rust. i replaced the tires. some of the plastic was cracked and one of the blinkers was cracked. I also had the tank recreamed which he included in the price. I also replaced the petcock. oh and he didnt have the side panels. all the gages and lights work. so far i am very happy. Also thanks to this awsome website and BassCliff's tutorials.
