DT125R FORUM

2strokes in general is jetted plenty rich, to make sure they dont seize.

I run my 94 R with snorkel removed, and the airbox opened slightly more.
Stock mainjet, and half a notch leaner on the needle. The mainjet is still plenty rich.

Stock header, and aftermarked end can, otherwise stock.

I have a Dt125re engine in my DTR 🙂 just electrics and tachometer cable need converting also did the kick-start conversion 🙂

@micheal-cox I have not found that the powervalve works properly in neutral.

Best thing is to take the exhaust off and manually set it and disconnect it from the servo.
