How odd. Smakbiam said what his understanding was that he heard and then that he perhaps worded it too strongly, and this backlash? Lay off. Reckless_Kelly actually provided some potentially useful insight on the runners then there's some pointless flaming. Of course there are other things to do. That is obvious. But that's not to say that replacing the runners wouldn't be a good thing to do. The original poster said he was looking for ANY AND ALL INFO on this and it hadn't been discussed before.
As far as FCRs being a great upgrade universally? They may be great but I will be damned if I am throwing down $800 plus dismantling my bike for that increase. For some people they're rad, but for me and my ~$3000 94 Monster? And I lose my choke, on a daily driver? Oh, hell naw, makes no sense for me.
Going by the same logic used against Smakbiam, DesmoBob's got lame heads since it's a 97, so he should "deduce that one would really need to do something about that as well."
Anyhow, here I am and so on, but seriously, Kalaazar asked for any and all ideas and Smakbiam threw one out there. No need to lambaste. (Note - not knocking Chris or his bidness, heard many good things. just this thread)
Anyhow, back on topic - cams are super expensive and hard to find. 944s are easy-ish to do from my understanding, and they go up on ebay periodically relatively cheap. Very reliable from what I hear. Rejet it. It'll bump the ponies some but it's not going to be beating the 4vs down or anything. Clutch? All in how you ride, and if you have the same gearing, shouldn't be noticeable. On a CR dropping tons of cash might not really be the best financial idea, but I have no idea what sort of shape it is in, or if you care about the resale.
That is all. Flame on.
