I unborrowed my bike's battery back from my son when I found that Mr. Forgetful hadn't cancelled my (cheap by SK standards antique) insurance & registration for the winter.
Installed the battery, poured a quart of gas in the tank, pushed the button and she fired right up.
Then found the Wolo Bad Boy was putting out zero dB because Mr. stupid's attempt to clean up the horn's extra wiring resulted in two ground wires and no hot wire.
Fixed that and it's 129dB again. Took a test drive round the block, not quite legal with no helmet, effin' freezing with no gloves and a shopcoat over a tee shirt.
But I think that what putting my rig on the road has really done is summoned the March Blizzard.
