I went to the stealership at 7500 miles and asked if the plugs needed to be replaced at 7500 miles and they told me change them at 12,000. Now I'm on the internet looking for the best price/plug to make my Connie purr.
So far my Connie has been to Oklahoma and Arkansas so far. I'm still tweaking my ride for longer trips.So far I've added risers , wedges, lowered the pegs and P3's and a V-Stream windshield. Next task will be a aftermarket seat.
