yes that is quite true, the bike would not fire without the cdi so im assuming it has tumbled down the road somewhere, I think the cdi unit was mounted underneath the tank or somewhere near the oil tank at the front of the bike. mine has it mounted underneath the tank but mines an 06 dt125x, you can find cdi units on ebay from time to time, just make sure you get the correct 1, or a tzr unit might fit but again you need to find out if it will work
