I have the same problem! If I find an answer, I'll be sure to let you know...

Sounds like you need a new needle. :nod:

 

[dirt bike dave]

A combination of small things might help.

Try turning out the airscrew another 1/2 turn. This will help lean out the low end and mid-range.

If the existing needle is not in the top groove, try raising the clip and dropping the needle one position. This will further lean out the mid-range.

Also, a mix of 40:1 will run slightly leaner than 50:1. More oil in the mixture = less gas, so the bike will run slightly leaner.
