i have a grizzly 660 year 02 . i have a problem , the clutch makes a noise like metal grinding when i let of gas and it do not hold itself back it free wheels . when i ride it for about a mile or two it stops and holds back grinding stops . it seems like the clutch warms up or breaks free and works ok . i dont ride it alot should i ride it more ? what could be wrong or do i need to grease something ?

 

I would definately stop riding it altogether until you figure out what's wrong... Remove the clutch cover and at least examine it to see if you notice anything wrong... (too much sand/mud/dirt, no grease... etc)

 

i did look at the inside but it looked clean did spray it down with water nothing come out . from reading on here sounds like i need to grease it . was fine before i got it in alot of mud .. looking at taking it a part and greasing it
