Default Exhaust valve question.....

Hey guys i have my 91 cr250 apart right now and i was wondering.... is the pinion shaft on the crank case (the one that opens the exhaust valves in the cylinder head) suppose to freely rotate back and fourth or should it be spring loaded. I have no spring tension anywhere on the exhaust valves... either in the head or the crank case and im trying to figure out where i should have it and if i should...... thanks everyone!!!

I believe it should be spring loaded and exhaust valve fit & mechanism is not easy to explain in words besides i suggest you get a manual from ebay for your easy reference and enjoyment...good luck.
