Hi everyone , well broke my 2008 prowler 650 H1 , went for a ride , no noise , can home restarted it to put it away , had a tin rattle in it then , tore it down , engine driven clutch was problem , back side of pulley with cooling fins was hitting the case ???? cleaned it all up , and chatted with my Arctic cat dealer , they had no idea why ?? the center insert in back part of pulley came lose ?? no TBS or anything about it ???? center is pressed in ?? $ 150.00 for back side of pulley , so not a bad repair , just unhappy with only 2913 miles on it ??? hope this helps someone else !!!! might save you a big bill on repairs !!!
