@calum .ye pal expansion chamber. Tanks for your help. I drove a dt 80 in 1990 and had it for 5 years. Now a good bit older. I am putting together a very clean dt125r I have had stored for 4 years... so just changing a few bits.. should be back up and running in a few weeks..Tanks for the advice pal..
You guys have given me a lot to work with...
No, I definitely won't be riding it anywhere when it's running like this.
I'll print off this whole thread and show it to my friend who knows a lot more about bikes than me...
Thanks
When I bought my bike carb was leaking from overflow pipe all the time, when tank valve was open. I opened the carb and the reason was that, the float valve was upside down! I turn it to right way and overflow stop immediately!!! Check that!
