Why backwards.

[Deleted member 1258]

Ouch! At least with a conventional bike the momentum of the rear wheel isn't driving the chain forwards.

Both times I managed to quickly stop the wheel and got off with just a squashed finger tip, still not nice but no major damage done.

DO NOT try and clean a motorbike chain with the rear wheel off the ground and the engine turning the wheel!

Spoiler: Warning; blood and gore!!

Because otherwise if we all did it it could upset the delicate balance of the Coriolis Effect, and the Earth would spin wildly off its axis and plunge into the distant Universe and oblivion.

This^^^^

Cycling maintenance 101.

This one's even better, he was cleaning his GSXR chain with a towel, on a paddock stand in 1st gear...

Picture links are down but he chopped three fingers off!.

It f*&%n hurts just oiling a push bike chain, but that's horrific. It's also one of those "I'd better watch out that I don't get my hand caught. Oh, it'll be all right" moments too. I do have a motorcycle, and have been tempted to do something not dissimiarl

I never go near a chain on a running motorcycle full stop, too much to go wrong!.

I knew a mechanic years ago when I'd just started who'd recently lost the top 3rd of his finger in the same scenario, lubing a chain with it in gear.

Bicycle oil is directional, so it has to be applied backwards, so it works when you are pedalling in a forwards motion.

What is this "push bike" you refer to?

Bicycle oil is directional, so it has to be applied backwards, so it works when you are pedalling in a forwards motion.

Only if you apply it to the tops of the rollers on the bottom section of the chain.

I've trapped my finger twice, both times whilst working on my fixed, not nice, makes an orrible mess and hurts.

Only did it once on my fixed - very lucky and caught just the tip of my finger. Hurt like hell.
