My predator has a tick in the top end when I cold start it then it goes away and only ticks wheevved up. The timing chain is very tight so I don't think it is that.everything under the valve cover looks good and nothing is worn. I have no clue, maybe a valve spring or something? has anyone else ever had this problem?

Your decompression mechanism on your exhaust cam will do that usually when your idle is a little low. If it is not that then I would check the timing chain according to it's service limits or just replace it.

Never mind sounds more like the timing chain.

I think it's the decompression lobe on the exhaust cam it has a lot of play in it. Is that normal?
