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 ?

It’s a 1990 r

Will a 2004 exhaust fit on a 1990 ?

How do you post photos having a nightmare with my iPhone

@Glynn123 what jet would you recommend?

Hello all
Just purchase a 1990 dt125r, one owner from new and in pretty good condition for its age. Just done the basics air filter plug oil brake fluids tyres
I am looking at a new exhaust, are the romne handmade stainless systems as good as they look ? £309 is fairly pricey but I hear the dep systems rot
Any advice welcome as the last one of these I had was back in 1994

@NINJA
Would that fit my 1990 ?
