got my 62mm pulley installed today.this thing is really nice,well worth the wait.also installed the PSK,didnt get any instructions with it so just went to needswings web sight and looked at their good photos. whole procedure was easy,although belt seemed a little loose. went for a test drive and immediatly threw the belt. after some experimentations i replaced the tensioner pulley with a 100mm pulley(NAPA #38002)end or problem.thanks a bunch for involvement Rudy.
