come on some1 must know

 

What do you mean "minimum cut"? As in, the least possible mass to take off for a beneift? The least possible to machine off? Physically, you can take off only milli-grams, if you wanted to. If you mean whats a reasonable amount to take off, it seems that the concensus is for a roughly 8kg flywheel for the best compromise. I will point out, however, that it's not the weight but the moment of inertia that counts when were talking about masses in circular motion. Imagine, if you will, taking off 4kg of mass from the center, will have a much smaller effect than taking off the same 4kg from the rim.

But honestly, make a specific question if you want a specific answer.

 

im having a clutch fitted
and am having the flywheel skimmed on the drive plate side
so there is a fresh surface
it has some surface cracks and need to know how much to take off
im not having it lightened

Much like turning your brake rotors, you would want to take off as little as possible, while getting rid of the problem. So if the cracks were 1mm deep, you would want to take off at least that 1mm. But you also want to make sure you don't take off too much, as you will loose integrity. There should be a spec on how thin the flywheel can be, and you don't want to go below that.

 

5CBY Dont forget its a double faced flywheel

 

?? wot do you mean double faced
have took 5 thou of it and there is still some cracks visible although only small
should i take some more of to get rid of cracks?
