Hello y´all! I just purchased a pretty darn clean 1975 Yamaha 125 Enduro. I believe it´s a DT E because it appears identical to the picture on this site, but how would one know? Their´s no indication on the title nor on the bike. Would anyone care to be so kind as to comment on this? Also, has anybody done any engine mods for more power on one of these? I had a 90 MX with a GYT kit as a kid; what a little screamer! (Not me, the bike!)
