man that looks like a lot of weight to add to the rotating mass I hope it doesn't kill the power that much
but sorry to hear of the zzz failing
i had my bad experiences with them that's why i went away from them
glad the 630 worked better for you
I registered to see the pics and ask where in cali you are. That looks absolutely SICK. I feel your pain on the chain, I just put a EK 530ZZZ on my 2005 Short Sand Car (Busa with a Mr Turbo kit on 5lbs). I'm curious to see how yours works out. That looks trick...exspensive but trick!
I snapped a ZZZ while my bike was on the dyno....that sucks about you wearing out the stronger chain but i guess its due to the non oring design and then you riding in the sand. Hope you get it figured out
