i know. a lot of reasons not to,,i have heard of and known people that the ind chain lasted for a while although it is bad about stretching. i would change to the 530 setup for my honda except when i got it someone had already put new 630 sprockets a o ring chain on it. the chain is short though since i redid the frame and i am just looking at the getting it going and change to the 530 stuff later when it is time to replace the 630. i can always buy a new mc chain and cut it to size,i am just a tightwad though and wanting to do it the old ways.
