thanks for the replies guys. I ordered the PRW flywheel this morning before i had read the posts. He has not steered me wrong so far and I asked to have the flywheel checked over before it was shipped to me. I decided to go with a different clutch this time around, a RAM 11" Powergrip. after a LOT of reading on the net over the last two days I chose it because I wanted a clutch that grabs and holds well at lower RPM and not just when the weights spin up to where they do their thing. a 462 is not a high revving beast and I am fine with a little tougher clutch foot compared to the soft centerforce pedal. the new clutch will come with a short bearing but I ordered a lakewood adjustable pivot ball to try and dial in my geometry better this time to get full engagement/disengagement and adequate free play. I had ordered one of those Ames clutch forks a couple of years ago during my build intending to use it but I found it so different from the stock one and did not fit the boot properly as you said john. i ended up cleaning up the old one and re-using it and selling the ames one at a swap meet. You can see the two clutch forks side by side about a quarter of the way down this page.
