I just install the V-force reed valve in my '02 YZ 250. What if any jetting change would be neccesary with this new intake. I would think it would require a richer main jet as the V-force allows more air into the combustion chamber. Am I right about this? Any changes to the jetting on the needle or slow jet?

Thanks in advance :cool:

You can generally go a step leaner all the way across the board. I was able to go 2 steps leaner on the pilot on my '00 KX250.
