I'm 16 and have been trying to fix my DT 50 October last year. Every time I fix something another problem seems to arise but I'm always able to fix it in the end. Although this time I am stuck completely, I have ordered a rectifier as there is a problem with the electricals but I cannot seem to find where the old rectifier is located to be able to change it. If anyone knows and is able to help me this would be muchly appreciated I love my bike and do not wish to have to buy a new one if I cannot fix her :'(
