I have a 2009 Honda Big Red with 3100 miles on it , two of the clutch discs in the transmisssion came apart and plugged up the oil pickup tube in the engine , it ruined the camshaft , the oil pump ,and all the little small pieces of clutch disc went thru the engine , took it to a Honda dealer , took over a month to get it fixed , over 2200.00 dollars for the repair , never would have expected this from a Honda , always used Honda GN 4 , 10w40 engine oil with a geniune Honda oil filter been thru two starters also and there was a stator recall on the machine too . really disappointed with this Honda Big Red , might get rid of it , I'm afraid it might happen again , considering a Kubota 1120D , just wanted to make all you other Honda Big Red owners aware of this problem , the Honda Pioneer has the same engine and transmission , BEWARE !
