@Calum lovely mate, thanks. What is the seal called do you know by any chance? Final drive seal?

Oil coming from the left crank case side / sprocket. Any idea why this is happening? Think it’s a seal gone..

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

Emptied fuel tank, just clean fuel. Cleaned it out also. Cleaned air filter also and still getting blocked... any recommendations? Shall I try size up the jet?

Ok sound, pictures of the inside of the carb I’m guessing? Haha

Would what I’m putting on my air filter have something to do with it?

@ringdingding and haven’t a clue about the condition of the inside of tank

@ringdingding no filter for the fuel, and very hard to tell as the hole is tiny so can’t make it out

Recently my bike doesn’t want to idle, I stripped down the carb and completely cleaned it as well as the jets twice. The idle jet was blocked both times I cleaned it, after putting it back together it would run as normal until the idle jet blocked again and then would have to be constantly revving it to avoid killing the bike at the lights...

Any ideas why this is happening?
Cheers guys

Never brought Silkolene before so watched to check before purchase.
