I have a 2002 400Ex with an White Bros e-series slip on pipe and K&N air filter with the airbox lid on(drilled holes),How is the stock head pipe compared to aftermarket? Is it worth it for me to get a new full pipe, I was thinking about LRD Pro4 series or something like that. I also did not jet my bike once I put the pipe on and I have all the discs on, will the jetting help that much with my bike?Also is putting an white bros cam in a good idea to get more power?I was told by my dealer that most time by boring out the cylinder he sees the machines coming back blown up, is this true? Any other ideas for getting power out of this 400 to keep up with the new 450's or do i dup it for a 450R? Thanks
