Its a good idea to get better valve springs whenever you get aftermarket cams, just so you dont have to worry about valve float when you take it to redline...
unless you want to have to worry about sinking one of your valves in those nice forged pistons

For cams like that you are going to want springs with a 180-200 lb. tension rate. I would have to say the Tibby's stock one's are around the 140-160 lb. area max since the factory duration is only 228/240 for the 2.0L and 232/240 for the 1.8L. This is of course a general guesstimate since I don't have a tension scale and an extra valve spring laying around.

Wow ok, I just re-read my post and that was what I get for typing at 4 am. I had just gotten done reading a very similar discussion on the Buell forums. We still use pushrods in those and I should sleep more...
