I just titled a few Indiana peds in IL with just a bill of sale. They need to look up the fact that Indiana does not title mopeds in the NADA book that they should have. If they still give you a hard time, try dealing with someone at the SOS bonding dept, they can do everything through the mail, just ask them to send you a title packet, you will not have to bond the bike. It will take about a month, $25 to IL DEPT OF REVENUE for sales tax and $134.00 to SOS for title and plates, they might also want a picture of your bike, specifically the vin tag.
