I have an '81 Interstate and mine is. It would drain the battery if I didn't ride for a couple of weeks. I ended up putting a toggle switch to it to turn it off if I knew I wouldn't be riding for a bit. Problem solved.
On another thread recently, the suggestion was made to get an ultrasonic cleaner (under $100 at HF). I and many others have had good luck cleaning the uncleanable with them. Good luck, Dave
I have a special needs son who lives with us. The side car would allow us to ride 3 up and take care of my having to hold the bike up as I age.
