Greetings, I recently acquired a Ditech too, and it runs and drives great. (Mostly) I rebuilt the top end after a seized Piston and failed head gasket. I only have a slight problem that sometimes, after driving it for a while and accelerating out of a curve, it stutters for a few strokes and then runs like nothing happened. It doesn't happen very often, but sometimes. Is that normal for those Ditech Scooters? Sparkplug looks great, and it's not too rich or lean. Thaks in advance
Running again after rebuild, good to hear! Many ditech scooters stutter, it is not uncommon. If everything is good as new it shouldn't stutter, but slight unbalance in the crank can cause it and the higher the mileage the more it appears.
@knetterman I was a bit concerned at first that it sometimes dies/stutters for a brief moment, when accelerating, but all parts are in good condition, so I will probably leave it as is for now. It's running great otherwise. Thank you for your time and help.
@@EinarLerschen its very tricky. This is the second time I come across this. No fault codes were present, but injection did not work. Tested by hanging the injector loose on the bike to see the fuel spraying, after fitting a known working pump and injector from another scooter.
@@knetterman Okay, guess Ill have to look into the fuel pump, compressor and compression first for my problems. Mine starts instantly but dies after 1 second, this have to be done about 10 times to get it to idle. Sputters like hell around 5-7krpm but if one gets above that, it can be driven.
Looks great! 😊

What are the symptoms of a failed ecu on these? Do they run at all?
