needle help

2 posts in this topic

I went with the stock YZ250f needle in the middle position. It cleaned up the midrange completly. Of course, this was also in conjunction with changing the other jets.

The MT-21 is a dual sport tire, so if you do any serious off-roading, you won't like it very much.
