The most lilkly thing to come off is a shifting dog. I mis-read your post and thought that those two photos were of different pieces. Now I understand that they are shots of one piece.

It is a broken shifter dog and from the wear it has suffered a lot of misuse, or something. All that has happened is that now the power is going through a different combination of dogs. This one was probably "leading" and took too much of the load, so it broke off.

Now the load has shifted and you have no way of knowing if it is better distributed, or worse. In theory all 5 dogs carry equal load, but that never happens due to manufacturing tolerances.

Upon a rebuild the technician can see which dogs carry the load by which has the most wear. I would change oil and sweep the bottom with a magnet to see what else is broken off. I probably would take it on the trip and just shift carefully, especially between 2nd and 3rd.

Usually the dog breaks off and no additional damage occurs, but sometimes that part can get in the middle of things and make quite a mess. It can lock up, but that is very rare and we only saw it happen once. It was on the bike owned by my genius mechanic. He crashed, I think, but wasn't hurt. Hard to remember, as he crashed often from over braking the front end. He repaired his headlight shell many times.

How far is your round trip?

Sorry not to have been clear.. When my old gearbox broke, I got a new one from Moto-bins. This gearbox was I think a overhauled one. My old gearbox from then is still in bits in my garage. When that broke it locked up my backwheel and had a big hole in it . Therefore I'm a bit worried about the hole thing.
And I'm not going for a long ride.
This bike is sadly my only one and I use it almost daily for commuting to work. We got this great rule here that motorbikes (and electric vehicles)are allowed to run the bus-lanes. I didn't dare use it todat and spent an hour in my Subaru instead of 15 minutes on my bike...
So what you think...Should I ride it?
I really want another bike so I can have time maintaining. Lookin at an '97 R1100RS with low mileage.

Hal, this is for anybody reading this forum.

Here is a very good example of why I highly recommend having a spare transmission sitting on the shelf. Then you are only an hour or two from being back on the road.

During our rather tame winters in CA, we would gather up our old transmissions and rebuild all of them. They would sit and wait for the summer customers to need them in a hurry. I would guess that we would sell 15-20 a season from our rebuilt pile. We graded them according to quality and priced them as such. We would pull the cover off the one just pulled out and instpect it to get an idea of what it would take to get it back running and what quality it would end up being.

A few didn't want a rebuild and they were willing to wait it out while we rebuilt their transmission, but over half elected to get a rebuild and get back on the road.

Did you offer a limited, 30-day warranty on your rebuilts?

Yes, we had an automatic warranty on all of our work. I don't recall the time limit, but it wasn't really a limit in fact. Once in a while we would find that we had made an error, or failed to correct something properly and would fix it even a year later.

Do you realize just how cheap it is for a shop to fix almost anything? We had spare parts that were nearly unlimited. While they had value, we almost never had any money in them. My risk/loss was only the labor.

Fixing our mistakes for free is a great marketing opportunity. I don't understand why more don't see it that way.

Duane we too used this sort of approach on anything we worked on. Most others, sadly did not. We got a lot of things in that had been "repaired" elsewhere where the real root failure had never been fixed and again caused the same failure the customer had seen prior. This was when we would get it. On those occasions we/I was responsible for pulling such a "boner" the root failure and the damage it caused were both repaired on our dime. These customers ALWAYS came back; all be it carrying other broken materials and machines in hand... :)
