whats the bore and stroke of the 425

 

The bore and stroke is 87.9 X 70.

 

425Xpedition,
What is a Monster Power performance kit and where did you get it?
I didnt think anyone was making performance kits for the Xpedition.

 

The Monster Power Performance Kit is from Highlifter. The kit consists of a K&N filter and pre-filter, Dynojet jet kit and Supertrapp IDS-2 exhaust. Supertrapp does not actually make a pipe for the Expedition, but the pipe from a Magnum 425 will fit with a few modifications.

 

what did your performance in hancements do for the
425?? was it worth it power wise?
