I run this larger CVF crank pulley. Their pulley kits come with an under driven crank pulley so I bought them all separately. Not sure if it would work with your other pulleys but you always could swap them all for the CVF versions, sell what you have to recoup some $$$

It's too bad they don't have a single groove version of that crank pulley. I also wished they had a set that overdrives the w/p.

If you recall, what water pump pulley do you run with that crank pulley?
