Hello World of Atv Users. Let me first start of by saying thank you to all replies of any type of advice
I Recently Tore down my Engine head on my 1995 bayou to diagnose an overheating issue , I found Blown Bottom jug gasket.
Upon Scraping the old Fabric Gasket off the lower engine case I pushed the piston down for better scraping access and it now it is stuck in place ,
Cant pull it back up freehand, Putt it in gear SL(1st) and Reverse but it will not turn back over, Everything was seemingly fine when i took it apart so
to lock all of a sudden seems unlikely. Thank You again for all you help

 

Cam chain has dropped off the lower sprocket and jammed between case and sprocket.

 

I will check that! it makes sense cause there is no tension on the chain, I will check soon and let you know thanks again for all you help

 

Thank you to Merryman The issue has been fixed I was able to pull the cam chain out the way it went in. Note to self,
tie chain to frame with wire and it wont loose tension lol Thanks again enjoy the riding
