Is it totally stock? Air filter and air box lid installed?
I would think its a carb problem. Either the air filter is pluuged up, or the carb jets are plugged up. Clean them both, disassembling and removing the jets, and cleaning all the passageways in the carb.

I had a 1983 yamaha dt80 years ago and that happened to me. Due to the fact that the gas tank is metal and rusts this plugs up the carb. I would pull it apart and clean the particles out. Make sure the gas lines are in good shape because I had to replace all mine because they would dry out and crack.

1978 DT 175 problem
Hi there,
I had some issues with this as well. But I couldn't get it to run correctly at all.
The solution is to completely disassemble the carburetor to just the body. Clean and de-varnish the carburetor parts including all the jets. My local shop suggested Yamalube Combustion Chamber Cleaner. That stuff works really well. It's a foaming cleaner that after the foam dissolves turns into a liquid.
Foam up all the components of the carburetor and let them all soak in the liquid overnight. Then clean it out and reassemble.
You'll need to get all new gaskets and o-rings but it's worth the effort.
