Stator and R/R Replacement on a 650G

Yes, I did bypass the wiring that went up to the hand controls. The overheating harness will not be an issue.

That being said, I did reuse the whole of the old stator harness to go into the new stator, including the ground wire that is meant to ground on the stator's mounting bolts; I've seen some people who've wired the ground up directly to the negative terminal to make sure the stator has proper grounding, could that be the issue here?

The stator isn't grounded, so that's not a problem.
Do you actually mean the reg-rec?
 
hey all, Im new to the site, just picked up an 81 GS650GL yesterday for a project. The bike was sitting for a long time due to a bad charging circuit so I started gutting it today, cleaned up the carbs flushed the gas tank, drained the oil, etc. I put the battery on a tender for reconditioning and charging and started digging through the circuit, it has a new R/R and igniter unit so that was good to see. I measured the wires off the stator and got on average about 1.6 to 1.8 ohms between each. I forgot to measure for gnd off the battery before I popped open the cover and oil drained, that was a surprise having never dug on that side of a bike engine. Is that a special oil or does it just take it from the engine oil?

I read a few posts about caltric stators on here as well as RM but also saw lots of bad posts off reddit, is it worth just going to fortnine and forking out the 200 for a ricks, Im not sure the stator is toast but it certainly is not the prettiest looking thing?

LMAR,

First, welcome to the site.

Second, this is rustyspoon’s thread to help him deal with sorting out his charging system on his bike. While your issues are relative, we didn’t want to confuse advice for him with advice for you.

I would suggest you make your next post a new thread up in the GS Owner’s Forum introducing yourself and your bike.

Take a look at the top 10 list linked in my signature for lots of tips to get you on your way.

To address your immediate issues:
Yes, the Stator swims in oil. You could have avoided spilling any by propping up the center stand’s left side on a 2x4. This and other helpful info is included in my own charging system sorted thread also linked in my signature.

Caltric, Rick’s, and Electrosport all make well regarded replacement Stators. I’ve heard of RM but haven’t read anything about them.

Then, after looking at the links I’ve given you, and using the site’s search function, if you still have questions, please start your own thread in the Electrical/ignition Forum.

Following any advice regarding fixing your motorcycle that you found on Reddit is not advised.

While this thread is technically for my benefit, I have no problems sharing my experiences in this thread.

During my experience outlined in this thread, RMStator has been great. Their best customer service has been over their CS phone lines but they've helped me with part selection and while anecdotally their DOA ratio is kinda high (One for me, two for Mr.humbucker) they've been really apologetic about it and super helpful throughout the whole process. When I first called about the out of spec R/R, as soon as I told them it was out of spec and how, they immediately directed me to start a warranty claim and to take pictures of my test. After I started my claim, I sent in all the details and pictures and called them 10 minutes later. They pulled up my email, saw the pictures and said, "normally we'd ask you to send the unit back to us for testing and we'd send you out a working unit, whether that's your original or a new one. Since you've already conducted the tests and provided proof, I'll get a new one sent to you immediately and you can return the dud after you get the replacement." An hour later, I got notification from the shipping company that they'd picked up a package that was destined for my front door.

The only thing you have to keep in mind is that they are based out of Quebec, so their business hours are 8AM to 5PM EDT, which translates to 5AM to 2 PM PST and some of their customer service reps have a small french accent.

I would definitely recommend them!

Another plus is that RMStator always provides a set of the plugs that goes from the harness to a particular part. I cut my OEM harness and attached the plugs from my R/R kit to those wires, and the bullet connectors that came with my stator came in handy as well.

Thanks, and yeah absolutely Ill go through your links, there is ton of good info on here and did not intend to jack the thread. This is my first older bike and never had to dig through the charging system on a motorcycle before.

​And thanks rustyspoon, I put some thought into it last night and I really should have taken a few more measurements before cracking open the stator, Im going to put it back together to verify a few steps I skipped and likely start another thread. Have some other issues (rusty tank) to deal with first.
 
The new R/R came in on Wednesday of last week. The quick test showed better results but not perfect.

Quick test results are as follows:
1) Key Off - 12.48
2) Key On - 12.21
3) idle 1500 RPM - 12.62
4) at 2500 RPM - 13.53
5) at 5000 RPM - 14.04
6) Key off - 12.52

All voltages are on the low side, but still within acceptable parameters. I've been riding it frequently since, and the new charging system has been holding up with no issues. Problem solved! Thank you so much to everyone who has helped me fix this issue!
