I bought an 07 rmz250 and just built pretty Much the exact same engine. It’s insane. The sound is off The charts. My son has a yz450f and although he can out run me ultimately, I leave the line like a rocket sled in rails. He is mind blow at how fast this rmz is now vs pre-build. It really is a force of nature. Mine doesn’t look as good as yours.....yet! All things in due time. Great video. Keep it up!
I have the same bike but with a custom yoshi header and a 450 tip. It has 50hp and is the loudest dirtbike i have ever heard, with a vortex ignition the throttle response is crazy!
