About two weeks ago I was reading on this site about changing the spark plugs every 6000 miles . Well , i checked my valves after the 600 mile break-in ... and had the plugs out at the time. Everything was alright so I've left things alone and enjoyed ridding ever since .
Now at 25,000 + miles I read that plugs need changing at 6000.
So , I checked the valves again with pulling the plugs again - left them a little loose at .010 and .012 instead of .006 and .008 ( they still don't rattle ) .
The plugs looked fine but I got new iridium plugs anyway (one range hotter-for the winter) and also a new air filter (DNA).
My 2016 V7 runs stronger than I think it ever has !

I did all the "Fixing" at the same so I don't what did the most good ?
Anybody else done any of the above ?
