I just finiished replacing the cases on my 08 (cracked behind kicstarter). A couple things have me puzzled. Number one, my Rekluse clutch doesn't work, somehow the clearance in the clutch pack changed and it now makes contact with the outer clutch cover, It never did prior. Also ocassionally there is strange noise when I cut the bike off, it sounds like air venting, almost a deep hollow whistle sound. The noise also occurs when I slowly actuate the kick starter several times. It doesn't occur when I remove a valve cover bolt and allow it to vent. The crankcase vent is open and venting. Anyone got any ideas...........I'm stumped.
