Hello all,
A while back I acquired a set of cams for my Rapide project, in about new condition. Based on the 'X1' stamping, I thought they were the Andrews / Megacycle X1 grind, with lift .330 and duration 254 degrees, measured at .050". These are described as "Improved version of Mark I profile. Touring profile" - just what's wanted.
Alas, my cams are not these. Examination shows they're pretty much a race cam: lift is a whopping .470", duration 280 degrees measured at .050". In addition to 'X1', they're stamped '90'.
Does anyone know their origin?
Thanks,
