Pulled the head off today. You can clearly see the blown gasket between the back two cylinders. I purchased a new Payen 1275 gasket from Worldwide to replace it with. Looks like it will work, but it doesn't quite match the old one with the elongated cylinder holes.
A few noob questions... I assume the surfaces need to be immaculately clean. Anyone have a preferred cleaning method?
I tried to be careful pulling the pushrods out, but on two of them I heard a sound like a falling bolt. Was that the tappet? Will that be a problem when I re-install?
I searched the forum and saw that some people recommend re-torquing the head after a certain number of miles, and one person that uses threadlocker. I didn't see mention of these in the manual. Thoughts?
Thanks!
