Welcome back, wondered were you had been hiding. Keeping busy on the road?

Actually no, my truck SCR system had to be rebuilt, and started getting low oil pressure. I have been working on the house, ol Rusty pick up and the BMW trying to not lose my mind looking at and wanting to ride the bike.

I finished it today.

After cleaning the surface very thoroughly first with kerosene to get rid of the chain lube and then aceton many times, I epoxied the parts one by one. After curing (about 24 hrs), I applied another layer to the sides of the supports. JB weld seems to be holding them very strong but I will see if it will hold in the days to come. After epoxy, I installed new sprockets and chain, and the new sprocket cover. I also changed the oil considering it may have been contaminated during this whole process.


Thanks for all the help everyone! Here are some photographs:

Hi, the same thing happened to me and was planning on doing the same fix. I was wondering how your bike is holding up?

Like glue I bet

Why does the chain come off the rear sprockets, Poor maintenance of the wheel bearings and cushion drives bad swingarm bushings or improper alignment of the rear axle sprockets completely rounded or big rocks?

Poor maintenance, it's my first bike and did not properly maintain it, lesson learned.

so everything I listed.
you let the wheel bearings and cushion drives go bad along with swingarm bushings and improper alignment of the rear axle sprockets completely rounded and it hit a big rock.

Holy that was a bad day.

Holding up really well. I rode about 3k miles since then, didn’t have an issue. Use JB weld and make sure you tighten your chain next time.

Thanks for hopping back in to confirm your fix is working.

Yea no problem.

I don't know what this guy is talking about; it was none of those things and JB weld is NOT a glue.

'Like glue' was in response to:
"Hi, the same thing happened to me and was planning on doing the same fix. I was wondering how your bike is holding up?"
It's epoxy, it certainly won't be holding up like a weld weld.

The other post was a plea for some input what caused the failure, so others could avoid the same problem.
sadly any of the things I listed could cause a chain to derail.

The case is toast. Pull motor, replace case, or entire engine.
