what are the major differences between the 2 clutches. i have both clutches side by side and they look the same. also, i notice the 250 pressure plate has lightening holes where the 500 those hole are not cut out...if shaving a few grams off the flywheel helps the motor rev easier, how would shaving a few grams off the clutch set up help?

Angular momentum is defined as:
(The moment of inertia) x (the RPM)
Since the clutch rotates at approximately 1/3 the engine RPM on most Quad engines you would have to reduce the moment of inertia of the clutch assembly approximately 3 times the amount that you would have to reduce the moment of inertia of the crankshaft assembly to have the same effect.
The moment of inertia (flywheel effect of a rotating object) is a mathematical way of comparing the flywheel effects of objects rotating about an axis.
So basically,,,,
9 grams off the clutch assembly would be roughly equal to only 3 grams off the flywheel. In effect,,,
Correct?

Yes, if you took 9 grams off the clutch assembly at the exact same distance from the center of the clutch (lets say at 2 inches from center of the clutch) it would be roughly equal to removing 3 grams off the flywheel at 2 inches from the center of the crankshaft.
Removing alot of weight near the axis of rotation does almost nothing to reducing the moment of inertia but it will act like you took one happy meal's worth of weight off of your butt or bike.
A flywheel will be the most effective flywheel if all of the mass is concentrated at the farthest distance possible from the axis of rotation.
So instead of shaving the outside of the flywheel, it would (in theory) best to take the material from the center point out to a few mm short of the edge. Or drill holes around it front the center out. But you can't really do that without compromising the integrity of the flywheel right? That's why most lightened flywheels are just skimmed across the face .0xx" and the outer side/ring is left alone?

No... your theory is wrong. do not take it off near the center. You want to take all of the weight off the outside of the flywheel. The problem is the outside shell of the flywheel is not very thick. I have seen the damage done when a flywheel comes apart. The outside of the flywheel was machined too thin and it takes the left side of the engine off when it explodes.
"A flywheel will be the most effective flywheel if all of the mass is concentrated at the farthest distance possible from the axis of rotation."
This is what made me think that you meant that the center/face of the flywheel needed to be shaved,,,
But alas, this is a clutch thread, not a 'flywheel lightening theory' thread and I don't wanna thread jack,,,,, I do enjoy learning though! Is there already a flywheel thread or what?

1. Removing the teeth from the clutch basket would reduce the moment of inertia the most but there is one problem with that.......................
Lmfao! Maybe just take every other tooth out,,, lmao no I'm jk jk

In the context we were taking about I was not referring to the ignition flywheel, I was referring to the clutch's flywheel effect. The clutch, a transmission shaft, a gear, a sprocket, the crankshaft, the water pump impeller, are funny shaped flywheels. Anything that has mass and rotates has a moment of Inertia or saying in laymen's terms: Anything that has mass and rotates is a flywheel or has a resistance to rotational acceleration. The Moment of Inertia of an object is just a number that we put on the amount of resistance the object has to rotational acceleration. Knowing the moment of inertia of an object allows is to compare the angular momentum, angular acceleration, and angular velocity of different shaped objects rotating at different RPMs.
Two rotating object can have the same Moment of Inertia (flywheel effect) and one object can be 1000 times heaver. It depends how far the mass is concentrated from the axis of rotation.
If you want to learn more about this subject it is in any physics book or engineering text book under the subject of Kinematics or Dynamics.
Ohhhhhhh!!!! I understand now! I may can't put it into words but I can see it in my head and understand
