Hi Firehawk - it's interesting that they had a pulley bearing go - that also happened to me on initial startup and I had to put a washer behind the bearing to provide some clearance between the bearing and the engine - once I got that sorted out (and put everything back together) - put about 100 miles on before the OEM fixed idler pulley began to squeak for the same reason - put a washer behind that one and it's been good since. I have about 1000 miles on it now including one track day & everything seems to be holding together pretty well. Still have more tuning to do which Sam is helping me with.
