NitroLuver the new motors should not haft to be be reshimmed for 30% but it is good to check to make sure the motor has the right shims when it comes in and to seal the motor to keep it form getting Air Leaks.

If you friend is looking for a good price have him send me a PM are you can do it for him and i will give you a GREAT price as i am a dealer for Axe Rossi.
