higer the motor has a loose chain slapin , tinny sound comming from
it. I cant seem to find from where any Ideas guys???

I hooked up an oil pressure gauge to my 600 . I watched as the pressure over a couple of months dropped off. About the time I thought that I need to take a look it jumped the chain. Since there is NO way to see your pressure this could be your problem.

It sounds like piston slap. Also, if you just changed your chain, the
tensioner to the cam chain tensioner may be dirty. Causing the tensioner
wheel not to be pushing on the chain enough.
