Will the power be much different on a 02 500 to a 06 450 much difference?

 

Yes,You should notice a little differance.........More if the 02/500 is a H.O.
............................I have two 2006 450's and the guys with the 500 carb say there is a some differance not too much ..........it's actually a 455cc........Caper

 

I'm not sure when the first H.O was made.......Did they have them back in 2002?....Caper..........

 

i think so

 

Yes, they were H.O.s in '02, and in '01 too. You will notice a difference between them and the non-H.O. 500s, so I'm sure you would notice the difference in a 450 too.
