I need to get a new primary clutch for my zrt so is there a good clutch kit to put in? It will be only trail riden. What clutch would you guys recommend? I was riding it today and it ran great then it would only go to 5000 rpm. The clutch had no cracks at the start of my ride but now there are cracks all the way around both sheves and the end of the clutch were the spring is will move up and down.
