Hello together, I bought my DT fresh and of course it blocked the rear wheel with my luck and most probably eaten. Since I don’t want to start 5 times I would have removed the engine and completely rebuilt it. In addition, it should be brought technically to a more modern level. I have all plans etc. for the moped however before going off I have various questions. – Are other motors and attachments possibly from the Dt250 or 125 with the de r 175 compatible, can I even insert the 250 engine directly into the frame? – The same question arises for me with the gear parts bearing etc. – Most likely the trigger from the piston eater was a defective oil pump. Does someone drive with mixture? Couldn’t be a topic to shut down the pump. – What is it like with tuning? is there experience with tuning parts? Does the device have another cracker / end pot there are any tricks from the ignition side? e already with the original parts difficult to find the right parts. Do you have good pages for OEM or also tuning parts? Parts numbers etc. Here my complete project: For links and recommendations I am very grateful! > Light & turn signal: Should everything be LED For this I have already selected all parts. > fender back: would like to shorten thus I need a 2nd > Krummer + Endtop: Have you experiences he gives shorter end pots/ sport manifolds with more volume > Carburettor: which carburettors do you use like this? Which are reliable and give a little more bangs on the bike? > Tires have I already picked out more smoother to be able to drive on the road a little more pleasantly. > I would have reinstalled all trains as they are all rusty. > Transmission: are there still original or OEM transmission parts as well as all seals Simmerrings and bearings? > Cylinders and pistons: I found the following: https://www.ebay.de/…/114220859366 > Screws: I need all the screw sets > Suspension: Which oils do you use? Do you get the chassis a little bit tighter with another oil? Do you have links to the sealing kits and bearings? As you can see, I need almost everything I am very grateful for every link, experience and tips.
