90s are fine, but if you have a choise, why not the 100s? Unless the 100mm will be to big up top? I'm not sure whare the Billet Flow pulley is, but I know for sure that a 100mm idler and the stock upper will not work togeather on the old style Metco.

No kidding? Wow, belay my last then. I just put on the old style with a 100mm upper idler, and a 2.80 upper pulley, it's pretty damn close. 3/16" max between the belt. lol, in fact for some odd reason, I was wondering how bad it would suck to get my finger smached and ripped aprat if I touched it some how. lol weird huh? Well, now that I think about it, the stock 2.93 upper is not all that much bigger, but damn, it must be real close huh?

If I spelled it wrong and you're picking on me, then oh well! :poke: I can't spell and I'm to lazy to use a spell checker for a Forum.

But if you really don't know, it mean, forgetaboutit. :beer:

Ass! :thumbsup:


j/k bro. :beer:
