I'm actually located in western ma. And since i can't take time off from work right now I can't make it to another dmv, but if i can figure out how, did you mark your registration as new or used? since you're using old bikes, did you bring a bill of sale for the bike and the receipt for the engine? Did they mention anything about being on their bike list? Any information you have would be greatly appreciated. try to be as detailed as you can. and THANK YOU!
