Just tops out, and won’t pull, did have issues when I 1st got it the battery was shot and the power valve didn’t move. But fitted new battery and was a lot better, but worried at the condition of the plug

Sorry not had the bike long it’s a 1990 125 dtr Swiss import. Have tried to up load some photos but no joy.
Looks like it has not been touched for years. Got a new plug air filter exhaust tyres. Changed the oil and it runs ok very quick up to 60 then dies a death

Afternoon
I have just pulled the plug and it’s balck and oily, I take it it’s running rich. How do you adjust the mixer ? Or is there something else that needs doing

Is the power valve controlled electricly ?
As my battery is flat and won’t hold a charge,

@Calum
I have just removed the power valve cover the power valve does not move when I rev the cables are attached, what could be the issue

Got myself a 1990 dt125r starts first kick and runs through the gears great but flat out struggling to hit 60 mph
Just serviced by me new air filter oil new full exhaust
Revs fine up to 9500 but just doesn’t feel right, last one I had hit 75 plus no issues
Any ideas

Do any of you guys use a fuel additive to help keep the carb and fuel pipes clean ?
