I have a '09 V Star 950 and put a Cobra FM on it along with high flow exhaust and cobra slip on. It really improved the power - especially since Yamaha tunes them so lean for emissions. Anyone do a similar stage 1 upgrade on a 8th Gen VFR? How much more power and torque did you get and how does it act when the VTEC kicks in? I love the VFR - best looking bike out there and the features and craftsmanship are the best - but I also like to get a little more power.
