@shaunp1912 The DTR's, unlike the E, don't generate enough power to operate the electrical components properly. A flat battery, even on an E, causes issues with the valve.
So that sounds like your problem.
No, all DT125RE's came with YPVS installed. Older 80's DT's, maybe with valves. I've seen a good number of 90's DT's without as well. But the majority of them out there have YPVS installed.
I already have a road dtr that one I was selling was a donor/project bike,my road bike however is a nice one,Costs me a fortune but I love it and she’s well worth it, I can’t seem to upload pics or I would get some up to show u
Oil capacity will be stamped on the case near where you pour in the oil it should be 750 ml in my experience I hate changing plugs on the dt I had to get a ratcheting spanner for it as it was a nightmare just take your time with everything although it’s basic maintenance all’s it takes is one snapped bolt and it’s s garage job so just don’t rush and it will be a really easy
@Glynn123 100% original unopened engine,it was the reason i bought it.Unfortunately don't have a pic from the day of purchase,it could be a highly recommended scrap yard candidate.
I have some old photos from the repair of the plastics,when i make a thread you'll see.
