Scott from Hillside has a FIX for the problem with the S&S 106" that includes new dome top pistons. He (Scott) has been very helpful. I will let you guys know how it turns out and will post my a copy of DNYO results as well.
I just heard from S&S tonight on this issue and they acknowledged "having problems" with these top end kits.....so far they have not offered me a refund.
