350 rancher Freewheeling when going downhill

Hi All, man I need help? I have a 05 350 4×4 Rancher that free wheels going down hill! I have replaced the entire Centrifugal Clutch including one way bearing? When I took it apart I checked the clutch plates and bands, they looked good, not new but good! I adjusted the clutch to Honda specs! there is no clutch slippage at all when riding the bike? there is no free spin when I turn the engine off, pull start works good? I am stumped!!! any help would be great!! thanks and God bless
