"Is it safe to do TPS/ISC reset if only in doubt? When not "necessary" so to speak?"

Perfectly safe. It's the same as doing a tune up, whether you need it or not.

Windwheeler, mine is a 2014. Several times I have experienced high and or surging idle which was corrected by the reset prodedure. Haven't had to do it for quite a while so its little brain maybe "learned" something!

LOL! That is too funny!

...probably, "or..., it learned something until the next power-outage...."

on the map sensor.... I combined cleaning the tiny holes & slightly chamfering them with a razorblade.
I then rotated it about 45 degrees(if you examine the sensor itself you can only technically rotate it a certain amount of degrees before it forces itself out of place.
The hesitation became alot better.  altho it is most certainly still there....
Im anxious for someone to develop a standalone type of ECU for this thing that will allow tweaking & sensor checks.

anyhow the mod works, and certainly helps.

What kind of spark plugs do my fellow downtown 300 riders use? Which ones fit and work the best? I was looking at ngk iridium cr7eix, but it said it would not fit my DT 300. Is that true? Let me explain... On amazon,you can put your vehicles in their"garage" when I put the downtown in and hit spark plugs( ngk cr7eix) it said this does not fit vehicle!!! Any thoughts and or recommendations would be appreciated

The NGK CR7EIX may not be the designated plug but it works fine.

I did the reset on the throttle today. It's made quite a difference. That, along with the replacement fuel cap, has made a helluva difference to its slow to medium speed rideability.

I'm going to change the oil and filter,again. It's been about 1,000 miles since my last one. I am also going to change the stock spark plug with NGK CR7EIX iridium. Hopefully I will find the time and complete by this weekend

I DONT think you can upgrade the no# on your plug. IF you have a 7, a BETTER plug is a BRISK=go to Amazon, type in performance plug. You will see 2 plugs 1 yellow, IF you have a NGKcr7hsa or another 7 rated plug, order it. Only 1 comes and its a match for ANY 7 plug. The no# is the heat rating, the more, the hotter, which can burn out ur engine over time if NOT match right. CALL BRISK in Texas and tell them your plug, if you dont have a 7 and they will give a match.
