want to rent a motorcycle

I am visiting dublin starting 7/7/09 from san diego ca USA. I tried to rent a motorcycle to tour the country side through a rental company but I just moved and with my new drivers license I can't rent a bike. I am not picky I just want a bike with 500cc or bigger. I have been riding for 16years and can ride anything. I just want to tour around and give you your bike back to you the same way you gave it to me just a couple of more miles. If you want to make a couple of bucks and only lose a couple of miles on your bike please let me know. I will be in dublin from 7/7 till 7/13. I was hoping to rent for three days 7/7 till 7/10 please let me know.
