I now own a 2011 Honda Fury for over a year and want to put open pipes on it .If I do will it hurt the motor if I make no changes?

Not if all you are changing is exhaust. Think of it this way, combustion has already happened, and with the exhaust you are not changing any of the stoichiometry of combustion. Change the intake, and you need to worry about this. My only caveat to this is make sure you have something for exhaust. Otherwise you will burn exhaust valves.

Thanks for writing back. What do you mean have something for exhaust?...
You have to run SOMETHING. If you don't and don't have anything bolted to the head at the exhaust port, it burns valves. It's an extreme take on on the low back pressure school of thought, to have no exhaust manifold of any kind.

I totally misunderstood you all the exhaust is there I just have open pipes with no baffle s.... As long as my spark plugs are a light gray tan color with no yellow I'm good to go correct?
