what would an acceptable difference in weights be? i was bored yesterday ( cause of lack of snow) and was weighing some stock cat weights. i weighted all my 85 grams and were out as high as 0.30 grams. doesnt seem like much but i thought i would ask. i had some old 68's there and they were as much as 1 gram out... that seems like way too much. i grinded very little off to get them to match in weight.

The closer the better. It probably doesn't make a ton of differeence but, you definately want all your clutch weights transfering their fair share of the load.

Good work on weighing them. I do the same thing.

Maybe we're just freaks? :eek:

I use a relaoding scale for weighing gun powder to balance mine. A 1/2 gram out of balance 4 inches out from the end of the crank equates to 42 lbs of out of balance at 4000 rpm and over 100 at 8000 rpm.
