[crazy Z]

How hard is it to jet the YFZ? I was used to jetting my Z. That was a piece of cake.

How will the YFZ be?

Patience, and a little study is the key.
You need a couple of metric allen keys, and a number 2 metric phillips for the carb inlet screw otherwise you'll strip it.

The difference in power is remarkable.

The YFZ is easier than the Z by far I think
