Well I had a new experience yesterday. The kick starter on my 06 YZ450 broke about 1/2 way on the shaft. Lucky for me one my buddies was on a WR so I was able to borrow his for the day. Now I am faced with the question of buying a used arm or new. Obviously a used one is a little cheaper, but is it worth it or will I be just buying another one in the not to distant future?
