Sorry for the long read.
I had a very dangerous event happen to me a few days ago which could of been a lot worse but somehow I got lucky.
Quick history. I drive a 2012 V7 Stone which has generally been fine since I got it, although it has its MG quirks every now and then but nothing major.
In Sept 2019 I noticed a small amount of oily residue on the back wheel and I suspected it was dripping from the drive train compartment. My bike was in need of a service so I brought it into my usual place to get it looked at. The repairs were done and it was fine to drive for the rest of the year.
I went away in December so it was standing still for about 2 months, came back and took it for a drive. Been driving it around slightly less than usual with CV going on but even so I took it for a 30km drive the day before the incident with someone on the back as well.
The next day we planned a drive around with some friends so I cleaned it up a bit and didn’t notice anything out of the ordinary.
I drove about 10 miles to meet up at friends house then continued to drive some more and got on a motorway. Going about 60/70mph I went to push a button on the speedo to clear the mileage. Around that time something happened and I very quickly started to lose power, then control which caused my back wheel to skid side to side as the speed dropped. Luckily I managed to keep control of the bike and must of dropped at least half my speed maybe more. I don’t know how I did it but I was VERY close to losing it. If the roads were wet I don’t think I could of counter stirred to stay upright. I really don’t think I pushed a gear down or anything when I hit that dial button in case people wonder about that.
I quickly pulled to the hard shoulder safely and noticed smoke coming from the drive train.
We were in a pretty sketchy part of the road so I very carefully drove on to get off the motorway to have a safer look. After stopping I then noticed that on the drive train/transmission that the oil plug (6) wasn’t there along with all the oil inside the housing.
I was shocked! And I still don’t understand how this happened. I then got it picked up and transported to my usual Guzzi mechanic.
There was a bit of very fine metal shaving on the wheel and what looked like some splatter marks around the wheel but it wasn’t thick at all.
I asked for a brief description from the mechanic its with and some photos which are below.
“Pinion gear chewed 107/8, 109 debris, 110 inner bearing surprisingly good, 111 inner race also surprisingly good. Bearing hidden under crown wheel, in 110, destroyed.”
My question is... where did the oil go, as there was none on the wheel or tyre? Where did the filler/level plug go? If they come loose, they drip on the tyre.”
If anyone can she some light on this please let me know as I feel this is all very strange and should not me happening?
It possible to change some internal bits inside the drive train to get it running again but tbh I am a little on edge to drive that specific bike. Should that be a thing or not?
