First off, I apologize but I'm having MAJOR trouble attaching photos to my post, why the f are we only allowed to post one picture per post? Here is the link for the rest of my pictures.
I bought my 82 GS750T a couple of months ago, with 41,xxx KM on it. I bought it from a guy who seemed to have something of a used car/bike lot going on his property, and looking back that should've been my first clue to run from the deal. But, I took the bike for a test ride, it hauled, stopped quick, and everything seemed to work on it, so I picked it up.
It originally had some sputtering problems taking off from a dead stop, it seemed that a cylinder or two weren't firing under load at very low rpms. After a little bit of fiddling, I found that the mixture screws needed adjusting, and since I've set them all and 1 and a quarter turns out, the sputtering problem has disappeared. I've since replaced the plugs in it.
I put about a thousand KM on it since purchase, including an amazing 400km camping trip with my girlfriend. The bike ran beautifully the entire time.

It wasn't long after that trip (the next time I rode it I believe) that I had some issues with it. It started up fine at home, warmed up, and I took off on my ride as normal. Stopped at the shop to pick up some chain lube, and when I head out to the parking lot, the bike won't start. It cranks, but not fast enough to catch. Luckily, the shop is at the top of a hill, so I was easily able to push start it and ride out of there.
I've parked the bike since then, as I'm sure there is something wrong with my charging system. And the more I read into it the more I realize i'm probably right. I bought a new battery, as I was unable to get my old one to fully charge on the battery tender. Performing the quick test outlined in the stator papers, my voltage across the battery terminals never goes above 12.2V, at idle, 2500 RPM, and 5000 RPM, all 12.2V.
After doing a little more looking around my bike, I found some things. (Pictures are in my linked imgur album) It appears my R/R has been replaced with one from a GS400... Is that a proper replacement? Are the R/Rs the same between the 400s and the 750s? And if not, could that be the source of my problems?
I also found that 2 of the 3 wires coming from the stator somehow had motor oil in the connectors, and it looked like 2 of the connectors had melted. So I stripped the wire back and replaced those connectors, still getting 12.2V @ 1500, 2500, & 5000 RPM. How did motor oil get on the connectors? They sit next to the battery and so far from anything lubricated...
I was going to pop the stator cover off and just have a look underneath to see what I was getting myself into, and the first bolt that I take out decided to bring the threads with it (as pictured in my album). Is that a helicoil that has already been installed, or are those the original threads from the block? Also pictured in my album is another of the stator cover bolts (still installed), notice that the part of the block that it bolts into has begun to crack. Do you think I'll easily be able to replace the stator (if that ends up being the case) given the shape of these bolts?
I'm just confused because the bike was definitely charging fine when I bought it, and after only a short while (about a month and 1000 kms), something has given out... So please, where do I go from here?
Thanks a lot for reading, and I appreciate any thoughts/advice you guys might have. Please help me move forward and get this awesome bike back on the road!
Cheers,
James
