I have to pull my 500R apart again and get the crank balanced like I should have done before I even put the new crank in. I was so discouraged by the thought of not having anything to ride, I was forced to buy an LT R450. I like it really well, but I really can't wait the have the big 2-stroke back. The 450 is alot easier to ride though, the 500R is kind of like wrestling a bear in comparison
