On my Yamaha R9 I can already tell the better shifting and you guys got ride of the dead spot between 2nd and 3rd gear from the factory plus I can tell it has a lot more power now then it did from before. It is so much bettrr with the fan kicking on a lot sooner is so much better. I give 2 Wheel DynoWorks an excellent review once again for this bike and from my last bike I had, it made a huge improvement on it also!! You guys do great work and I would highly recommend you to anyone I know!! Thank you again for your awesome work!! Keep up the great work you all do out there!!!
