leaking shaft boot gs1000

oh,my mistake. I am thinking per GS650-still, it's pointless staring at the boot.

Or whoever was in there before this guy got the bike used the wrong oil at some point. Dont think it would be a "serious" issue as the gears were still getting lubricated. But in a perfect world there should be gear oil in the secondary.

The boot is to keep dirt out, not oil in. and yes it's motor oil. The gearbox shares it with the engine.

Why haven't you undone the boot and looked?

Actually it should be gear oil. The engine/transmission and secondary gear area are separated by oil seals so no engine oil should be mixed with the secondary gear oil. If there's engine oil in the secondary area then you have more then one seal leaking.

could it be a corroded rubber boot?

This should be your bikes service manual. And the secondary drive gets gear oil and not engine oil.

Only thing that can let oil get in the boot is a bad oring on the gear flange. There is also an oil seal around the output shaft.

here is another photo from the drivers right hand side, pretty much the same photo as last. you can see the drips only small, but the boots covered in shiny oil. i should add that the drive shaft has never been serviced by me or the guy show had it before me and the bikes done 70,000 kms, but runs very well. i cant really tell if the leak is coming from the rear or front end of the boot. in the photos it kind of looks like the rear. but im pretty sure its engine oil not gear oil. as its engine oil colour and smells like it. but perhaps the last owner just put engine oil in the driveshaft. il check the driveshaft oil level soon.

Hi,
my 81 gs1000 is leaking engine oil (i think so, as it smells like engine oil) from the shaft boot. its a slow drip, only about a few ml a day. could it be a corroded rubber boot? or faulty o rings or something to the transmission?20161105_104500.jpg here is a photo from the drivers left hand side. you can see the oil drip is only a small droplet hanging off the end of the rubber. but its managed to make a nice little pool underneath over a few weeks.
thanks
