Hi there was wondering if anyone could advise i have just got my self a DT 125 LC 3 the 1986 model. i have had a lot of trouble keeping it running and have nothing left to try apart from the CDI unit, i have got hold of another CDI but it is a different size. the original has 2 plugs and 3 singles and yet the one i have picked up only has 1 plug and 3 singles (green plug missing) yet i was told the Unit was from the same model of bike. would it be safe to try it and would not having the green plug have any impact. i havnt traced it so i dont know wot it dose. would be grateful for advice if anyone can help.
