Has anyone replaced the S&S motor on M3W ?
What would be a good replacement Option if any?
More advanced quieter and more powerful engine than S&S ?
Just a thought.
How much power are you looking for?
I have the stage ll motor kit and I at times have a hard time now keeping the rear tire from spinning. You can do a stage III kit. It comes with 128ci jugs, hotter cams , new heads, larger throttle body, and ECU. But like I said before I have a hard time hooking up as it is with the stage II kit.
