CR500 Pipe

(1/3) > >>

BigGreenMachine:
Will it work on a KX500 motor? Rob power? Seems to be the way most go when they do a motor swap to the 250 chassis. What do you guys think?

gowen:
There has been research on this issue by AJ and hangtime(?). I believe it works, but you have to change the bend. I have a friend that is doing this now and is welding the bend from his KX pipe onto his CR500 pipe... He says it will work.. There is a post here about it..

BigGreenMachine:
Well what I'm really curious about is how it would affect power delivery. Being that the two motors are different bore and stroke I would think using a pipe from one on the other would limit power somewhat.

BigGreenMachine:
01 CR500 89 x 79
KX500 86 x 86

gowen:
It will effect performance, it could be better or worse.. The longer the stinger and section it seems the more mid-top range. I'd guess some low power gains using a cr500 pipe and loss up high.. Here is where it was discussed here.
