I think an easy mod would be to bob, or shorten the fenders. Quarter fender on the back and a little less on the front. You may have to move the fender struts for support.
Welcome to the forum. I have one of the ipods with an fm radio. I listened to it at work and on bike rides and motor scooter rides but the rechargeable battery kicked the bucket. I guess it requires some reassembly and soldering to replace it.
Cool. When your smoke detector alarms, I guess it sounds like a Stuka siren. (The Luftwaffe added sirens to the dive bombers to inflict even more fear on their victims.)
