Pissing fuel everywhere.
-
Recently my DT has been pouring fuel out the overflow, when it’s at idle or even when I’m going along. I have taken apart the carb (just the float bowl) to have a look to see what’s happening and seems to be the float bowl getting stuck but not a clue why, cleaned it put back together multiple times and still happening. Best thing to do would be completely strip the carb and clean / replace anything if needed to? Or buy a new one?
Seen a service on EBay that does this but for £50...Also due to the fuel leaking, I left a junction and creating a small puddle of fuel that I didn’t know about I lost traction when I went over it and dropped bike which hit the exhaust, ripping out the studs... would repairing the threads or installing new ones be easy to do?
Cheers

It could just be the carb has got gummed up, especially if you haven't dismantled it.
Taking it off the bike, dropping into a vinegar bath in an ultra sonic cleaner should help. Then reassembling it. If you're not comfortable doing that, then paying someone to clean it will have to be your option.
With regards to your exhaust studs that's a difficult one.
The exhaust studs should be removeable, but if you've damaged the housing then it would be very difficult to repair. I'm not even sure if a helicoil will work due to how much material there is left, so your best bet would be get a new cylinder.
Some photos may help here.

I have a 2001 DT125R, which is just under 5K and kept indoors. Looks like new, but last year,.. I could not get it to turn over. Skipped riding last summer due to lack of time to work on it. Was doing some cleaning and decided to spend some time. Guess what, started right up!
Then, it pissed gas all over me and my floor. Soaked it up and no gas left. It had been a couple years since it started... so I figured it needed a good rinse, even with the old gas.
Couple of hours later, new battery and a little more gas later and it started up with no issues. Not sure if it is related to your issue, but I am thinking it was well flooded last year... backed up even.
I suggest letting it all drain. put in a little more gas in a few hours and try starting it up again. Worked for me today.

Regarding the exhaust studs if there is still metal left where they came out you can repair them. I'd recommend using time-serts over helicoil as it's an actual new threaded insert rather than a coiled piece of wire. If the cylinder is badly damaged it will need to be welded to build up enough metal to repair.
You might be able to pick up another cylinder cheaper than the repair if very lucky
