I'm in the process of doing the top end on my 2000 CR-500 and would like more power from mid to top. The bike is stock with the exception of an FMF pipe / silencer. Does anyone have any experience with the V-Force or Boysen Rad Valve? Oh, I also am planning on getting Eric's Mo better porting this winter so I would hate to waste the money on the rad valve if it doesn't work well with both stock porting and Eric's porting.
Thanks
