If that is what you want, Bikes in the House, then so be it ! ! ! !, wife doesn't like it, she can have the back porch all to herself, or she can be in divorce court ! ! !
CHAUVANIST ATTITUDE ! ! ! !
I am very careful about any of the bikes spotting their territory, and never start them in the house, unless tailpipe is pointed out the door, or pipe tube extension on the end to take noxious fumes outside is on there.
