I have a 2009 Brute Force 650i. I bought from a salvage place with only 98 miles on it. I had a mechanic make the necessary repairs and everything works with the exception of one problem. The shift linkage can't be adjusted properly. If I adjust it so it will shift into reverse it will shift into low but won't engage. If I adjusted so it shifts into and engaging low the opposite happens in reverse. It also has a tendency to jump out of high. I was told that the shift linkage could be bent but it looks straight. Any suggestions.
