Hi All, yesterday I was tooling around the yard for about an hour beating on my rappy pretty thoroughly. It appeared to just kind of stall then when I attempted to re-start it, it seemed like there was little compression sound happening. I'm wondering if people have run into this after heating them up pretty good. I love the performance of the raptor but it seems tempermental compared to the 03 400ex I had. Any thoughts would be appreciated. Thank you

 

Could be many things,but if the valves are to tight, maybewhen it gets hot they dont close all the way, making you lose comp.
