Kawasaki FR651V Quiet cold, after mowing sounds like lifters need adjust ( Help )

How could loose tappets NOT affect timing ? It slightly delays the valve event.

And I agree better a bit loose than too tight. We'll see what happens, after a long talk with my Dealer. They convinced me to bring it out to them, as I still am under warranty.
 
When you performance tune side valves you grind the cam for a delayed and slow opening, substantially higher lift and early rapid close just before BDC.
you also increase the inlet tract to get better velocities .
Timing is 100 % a spark thing .
the only difference valve timing makes is what % of theoritical fill you get and how much fresh charge gets sucked out the exhaust.
 
Well, when my Dealer gets done doing a valve lash adjustment (warranty) job, I hope to be good again.

Kawasaki says adjust @ 300 hours, which I only have about 77 hours, but they agreed let Dealer adjust the valves, it is fully coverd under warranty.

I thought the Kawasaki manual wanted valves adjusted at 50 hours.
 
Not my engine family. And this was confirmed by my phone call to a Kaw Tech there. Plus my periodic maintenance chart.
 
Got my Z back Monday, mowed with it today. So Sweet.

Changing the oil back to 30wt this weekend.
