upon the initial break-in being completed should I have the engine checked for valve adjustments and so fourth...........or is this engine built somewhat like the z400 with the single overhead cam?.....................................

 

The valve's dont need to be adjusted or checked, however you could check them just to be safe. They're set up so they dont go out of adjustment..it doesnt say anywheres in the manual about it..so its your call..lol..

 

I would call your dealer.They SHOULD know if there is any adjustment and when they should be done.
