Hey there I've got a VTR1000F - 2001 model which i love. It has a set of High Rise Staintunes on it which i believe sound awesome. (does anyone know how much, if any they increase horsepower and torque). They where on there before i purchased the bike 2 years ago I am now wanting to tweak it a bit to get some extra power and touque without spending a huge amount of money. I am thinking of maybe putting a jet kit and a high flow filter in it and maybe put it over a dyno. Can anyone tell me how much these will increase performance, approx. cost and whether there is any down sides to doing this.
