I just went through a complete refurbish of a 1975 DT400. These things are hard to find parts for. Took me 6 mnths. If you have the time and drive it`s a good bike. Don`t know what you paid for it. I paid $700.00 for my 400 and wouldn`t sell it for less than $3000.00 You can find what you need if you search for it. If you complete the project? GREAT.. If not? Sell it on EBAY
