What primary springs are you ZRT guys running....assuming stock clutches, what spring are you running to get the engagement ~5000 rpm? I need poundage specs...colours won't do me any good. It is for a 97 ZRT 600.

ok...thanks. I guess I will tell him to get a yellow green then..because that spring had his engagement at about 5000rpm. Thanks alot. I just wanted the weights as a reference point.

Rocketman, in your previous post you said he thinks that his weights may have been shaved and notched.  If that is true, he will still need a stiffer primary to keep his engagement up.
As I said before, the HPE orange spring(similiar to the cat orange and white spring)would be better IF he does in fact have notched weights.  Just something you may want to have him check....
   If nothing else, use the yellow and green and put stick weights back in.

Yeah..he thinks they are shaved and notched....but I believe they are stock. Anyway, he has a yellow/green in there right now, so that is prbably what he will put in. Thanks guys
