Might have to do with the fill rate of the grease. Mine spins like a top.
That very well could be the case. I put them on stock when I purchased 'em. I have a pair on both bikes. The cranks are hands down the best change I have made. I noticed a difference immediately.
I was pretty disappointed in the BB, but I did not take it apart to check the grease. I couldn't get mine to make more than 3 rotations. That is why I swtiched.
