I am about to change the timing belt on my fourtrak, as I am unsure when it was done last. I just wanted to get a consensus on whether a belt alone is ok or whether the idler/tensioner is recomended at the same time. Belts seem regularly available cheaply, but the kits seem very difficult to find, and expensive if you can find them. Just thinking if the idlers feel ok should I be ok to just do the belt. Thanks.
