After some expert help!

You haven't by any chance left the choke on have you.
I remember when I first got my DTRE I had this exact same issue. Would start fine from cold, forgot I left the choke on, then ride around it wouldn't idle. Once it died it simply wouldn't start.
That would be my first place to look.
Was the carb leaking before or after you dismantled it.

I may have left the choke on yes, as I came from a WR I maybe forgot to turn it off. I'm not sure if it was leaking before or not although whenever I would take it out the garage in a morning it stunk of petrol so could possibly of been leaking before. What damage could leaving the choke on cause?
Thanks for your reply!

Thanks I will give it a go.
Any idea on the carb overflow? Tried tapping the float end in case it was jammed but no luck. Thinking about taking it to a garage and having all the seals replaced. Noticed a threaded bolt on the reed block, would this cause an air leak?

@mightyman I've only known 4 strokes to make that sound

I'd say piston rings at a guess maybe just a cracked ring would cause issues

@andrewj1680 thanks

@ricky0115 markings on top of the piston should give you the size or measure the bore with calipers, either way it's the head off, not a big deal. Personally think your problem lies elsewhere but expect to be proved wrong, see what the garage says, hopefully something simple. Good luck

Just had a quick Google and first couple of results suggest worn rings / not correctly sized piston, which makes perfect sense because the sound will be the air squeezing through the ring seal when compression is happening.
I suppose this means my bikes could have been a bit down on power not having a correctly sized piston
-
I've had this before on a high mileage DT125R and due to being poor I left it with dire consequences. Basically the piston tried to make its way out via the exhaust port. I went from a standard bore to 2.00mm oversize in one go which made me cry when I realised.
