I hope this is the right area to post this. This is for my 88 FXRS. A couple of weeks ago, I fired it up to let it warm up and circulate the fluids. After about a minute, it dropped a cylinder. I checked the normal stuff first, ask to no avail. After pulling the front rocker cover off, I found the culprit. The front bolt for the valve train came out, and was now wedged in such a position that it had the exhaust valve wide open. Obviously, it only took a second for it and the piston to become close friends. After tear down, the only problem I could find, was a bent valve. New gaskets and a valve, easy fix. Everything went fine, until I started to put the rockers, and the rocker shafts, back in. The push rods must have grown a little bit! I have to partially compress the valve springs to put the rocker shafts in. I checked to ensure that I didn't inadvertently switch the pushrods, they are in the correct position. I replaced the head gasket with the appropriate thickness as well. I'm at a loss right now. Any ideas about what I have going in here?

 

sounds like the lifters are pumped up, they need to bleed down

 

No idea but if what bik and chrome says doesn't cure the problem try the Evo forum.

 

Ok, thank you very much!
