Hi there, I bought this 650xt with aprox 1300 miles And 129 hours on it from an older gent who basically putted around with it checking crops. It seems to run and drive fine but when I go to shift it into any gear it grinds the gears a bit then goes into gear. I took the clutch cover off and blew quite a bit of dust out of the clutches. If you start it up in neutral the belt turns the secondary fast enough that it grinds when you shift it into gear. Does this mean the primary needs servicing? The maintenance required does flash on the display when you turn the key but probably not related to the shifting problem. Any suggestions? Thanks
