12.5:1 Piston and exhaust cam swap!
 
Hey guys I noticed the forum is a little slow these days so why not start up another thread. I searched and kind of got some mixed reviews on the piston. Currently have an exhaust cam on order with the BCS sprocket. So I’m thinking of going to a little higher compression piston (12.5:1). Is this something I’m actually going to notice or is it just a waste of money? My stocker probably has 80 hours or more on it so it’s probably due for a replace. Current mods are 2014 ds 450 Xmx rossier full system, BCS intake ring with filter, air box lid off , power commander 5. Thanks !

You'll notice it probably on the lower end more than the top end. Combined with the exhaust com you'll have a good combo.
