Removed wrong underside engine bolt - Help

[dscaptno9]

Help ! ! I accidentally removed the wrong underside engine bolt (14mm) when performing the first oil change on my CT125. A spring and smallish round bar with holes fell out. what is the order / procedure for putting them back properly ? Thanks for any assistance. Rich

on the left side of the bike? thats the cam chain tensioner. tube with holes 1st (should eb a plastic button on top), then spring small tapered end down, then bolt. before starting motor, disconnect sparkplug, and spin the motor over for about 10 seconds to let the oil pump fill the tensioner cavity back up some. (yes its hydraulic)

Yeah. Looked like the oil drain plug to me too. The copper washer was the clue. Then I saw the other bolt and looked it up in the service manual… I also took the skid plate off to have a good look.
