It is a gas gas ec250, 1999 running std sprocket size. 14 front and 48 rear. The carb has in 170 main and 38 pilot.
I was thinking maybe jet size.
What do you guys think?
The problem is usually the needle selection - most use a better needle in combination with a richer pilot.

Typically - you want to be 178 main and 42-ish pilot with a yamaha or suzuki needle. This may vary from country to country due to differing fuel characteristics. Are you running a good premium fuel?

Also, given the age of the bike - it wouldn't hurt to check the reeds and replace them if needed.
