’96 Fourtrax 300 – kick start after cam chain install question

Hi all.

I just changed the cam chain in my ’96 Fourtrax 300 2×4, put everything inside the clutch cover back together, and installed the cover. Before I put the rocker box back on, and before I filled it with oil, I wanted to check to make sure the kick starter and everything else inside the cover was working; however, when I pushed on the kick starter, it seems only to free wheel the clutches, but not the crankshaft (which is what I saw it doing before I replaced the cover). My question is, do I have to also fill it with oil, and put the rocker box back on before the kick starter will work, or should I stop where I am, take the cover off, and look around? I’m sure I put everything back together correctly, so I’m not sure what the issue is unless this is normal given I haven’t completed the job just yet.

Thanks.
