Hard to tell after not riding the bike for about 3 weeks. That is the time the Vortex needed to find its way to me. Overall I like it I have 10 different maps to choose from although I rarely switch between them.

You have to jet richer when going with a more agressive curve.

I have a HPI on my 144 that has been mapped specifically to match the porting.

It gave the already good performing engine a real shot of addrenilin. It just made everything livelier if you know what I mean.

Stimps has one on his YZ 250, you can check out the performance on his posted dyno charts in the stickys.
