Hi Tom,
Thanks for the detailed info, I now understand that it is very important that the variator and rollers must match the driven pulley and spring to get co-ordinated movement. I have 2 variators, a 115mm dia unit marked F.S & FCC-TW & KDU, I purchased this one and it was called a race variator with 13g rollers. The Hammerhead came with a 108mm dia unit marked FJ & AAB & 6YG with 14g rollers, I think this is a std unit.
The question is which power spring and which variator / roller combination do I use?
I have sent you a couple of e-mails about parts please reply when you get a chance plus advise suggested combination.
Thanks for all the advice and help.
Best regards, David
