I see this was posted on Psychic Wednesday . . . .

All we know: It's not a Honda motorcycle. I guess we don't care which
side the steering wheel is on.

Do a tune-up run a bottle of fuel injector cleaner through it and stop
warming it up on the driveway. Also search Google for 'italian tune-up'.

Start it, adjust the mirrors, and DRIVE.
