Hey I'm sort of new here but have been a long time mechanic. I bought a 400ex that was totally disassembled and now I am working on getting it back together. I need to know if there is a gasket that goes under the rocker cover. I didn't take mine apart so I didn't know. Plus my gasket kit did not come with one so i used rtv. I had to readjust my valve clearances also in order to get enough compression for it to run. Secondly when I first started it up I had the plugs on the left side of the engine removed for looking at the timing marks and once it fired I promptly got a bunch of hot oil sprayed on me. Is the stator supposed to run in oil like that? Thanks for the help in advance.
