2014 T100 Newbie Question

Hello friends, forgive me if this is the wrong spot but advices needed! first time poster. 3 questions if i may..Any/all answers greatly appreciated!

Q1/ Seeing as so much of the maintenance is mileage OR time related, how much import should one give to the 'time' side of things. Anything else needed on a 2014 T100 with 3600miles other than tires/plugs/oil/filters?

Q2/ Am i imagining this? I love the sound of my NH Togas - roaring is better than purring, but my question is without AI removal or remap am i correct in thinking i'm better off sticking to OEMs for optimum performance/back pressure and fuel economy?

Q3 A/ being an air-cooled twin, at what point is too much slow speed 1st gear friction zone work enough (esp on a hot day)? Id hate to burn out the clutch or overheat the engine. Thinking 8 hrs slow speed rider type courses.. would a w/cooled bike better?

thanks so much for any replies and bright moments!
