Damn, $120 is a lot. So you basically gave him one of your keys. I guess unless he lives nearby, there shouldnt be any worries. Did you sell everything together or just solely the trunk? How come you sold yours and how much did you get if you dont mind?
The next ride you go on with a group of Valkyrie's, ask some of them to try their key in your ignition.
You will be surprised how many will unlock and start your rig.
Honda did not have all that many key sets when they built these bikes. We tried it one time in Custer, SD during Bike Week. My bike was setting on the main drag and I'd hate to estimate how many tired it, but 4 succeeded in turning the key on.
