I do not know of this project, but I use a Grok harmonizer for a long time.
Grok dir a very fine job, and very industrial looking. Since it's passing, Katdash ( www.katdash.com
) have taken over building and selling.
IMHO, if you do want a perfect synched bike and do not want to get your fingers involved, this is the way to go !
Just my 2¢
