Hi guys,it might not be just the jets,I have a Dt that when purchased it had stood for 10 years and the fuel goes like varnish and eats away inside th carb,have it ultrasonically cleaned by ur local bike shop and have it blown thru with a compressor as well ,then as the guys say above
-
Cheers for all your help guys. Carb is getting cleaned at my dad's work and getting put back on Friday so I'll let you know the outcome!

Now then,
Got the carb back after it was stripped and cleaned and it kicks first time now but the revs go through the roof. Idle screw seems to have no effect, this bargain bike is looking less like a bargain day by day haha
-
It's an Air leak, but try and renew the choke seal and gaskets in the carburettor body first. Runaway revs on idle indicate a lean condition. Is it harder to start?
Pilot Jet should be a 25. This determines the fuelling at idle and slightly over.
Keep it real

@Darty before the carb was given a good clean it would only start with a bit of spray through the air box. Now it starts first kick with the choke on but goes to about 5 - 6k revs and bogs down after that. Looked for a rebuild kit and it's near on £100!

Heres a rebuild kit for less that half that, including shipping: http://www.ebay.co.uk/itm/yamaha-dt-dtr-dtre-125-x-Mikuni-carb-Carburettor-repair-kit-dt-125-/272339199626?hash=item3f68ae668a:g:LSMAAOSw0UdXre0p

Evening,
Just thought I'd let you know the bike is running sweet as a nut. Hadn't started in a day or 2 after it was idling at 3-4k. First kick this afternoon and it started and idles perfectly, it's mended itself!!
