Apart from oil leaking from engine block, the engine runs good when it runs.

Oh is it? I did wonder as it has a tread can’t remember was awhile since I took it out. I was thinking it could be blank cheers mate. 😊

Moral of the story from this I can see is

More horse power = power maintenance worm with pustion changes probably more regularly

Keeping the dep exhaust carbon reeds and sprocket changes seems like the best for performance with out risking blowing pistons more frequently

I did see a video on YouTube on how to make two stroked more powerful but with this there was a risk of blowing the engine maybe if you want a fast bike just get a bigger one?

I wanted a yz road legal but for daily use I can imagine these get warm and aren't really good for road bikes sure for the track for a couple hours it's all good

The dtr is a true work horse in my opinion
