Do not ride your slightly lowered motorcycle over a speed bump with an embedded bar running along the top of it, even at a slow walking speed. You will hit the bar, it will rupture something in the bowels of the engine, and you will be sitting on your bike wondering why there is oil pouring all over you, the ground and your tyre. Especially, do not do this 100km from home, on New Year's Day, in an area with absolutely no mobile phone coverage.
If you do do this, be aware that it will cost a small fortune to get the bike towed somewhere safely, the bike will be in storage until the following Monday when the bike shop finally opens again, and the odds are that the actual damage to the bike will be less than your insurance excess anyway, so you will most likely end up footing the bill for the whole misadventure.
It is, however, a fabulous way to get an overdue oil change done - particularly as every single drop of oil in the engine ended up under the bike within about 2 minutes of the event. I do not advise this as the ideal way, though.
It also gets Housemate out of the house for a while, when she has to come and pick you up from Upper Outer Woop Woop. Thank heavens the gift shop were willing to let me use their landline!
My poor bike!
