Aren't kids fun :)
A friend of ours' son was on his XR50 not long after he got it & was racing around in 1st, quite content. His dad went up & said, "how about I change it into 2nd now" & the lad replied, "no thanks, dad, this is fast enough". We were all in stitches over that one. Then when him & his sister swapped bikes, we were all thinking "oh, no, now he's going to want to swap permanently" but no, he turns around & says he prefers his bike (his sister's CR50F is derestricted, his XR isn't). She preferred his XR50 to her XR70, just felt it was faster, so the 70 went & the CR50F arrived (now it's hard to stop her riding whereas the 70 only had a couple of rides on it).
Kid logic, I dunno - us women get harassed about not being logical, kids are worse hehehe
As for why didn't you get more response to your thread? This forum has less traffic, yes, there are lurkers, not a big deal. However, when I did a search for the latest threads, I saw the topic "proud papa" & thought, great, another mini-dad going on about how great his son is, but doesn't ride himself, I'm not going to even bother looking at that thread. (I was also expecting your son to be on a YZ doing MX after seeing your nick).
Don't get offended, I'm just telling you what I first thought, till I read your other thread & realised I was way wrong.
As for posting pix & video, you won't be able to as you're not a subscriber or support team member - see link at bottom of OldGuy's signature for more info. But you will be able to post it elsewhere & then post the link here.
Congratulations on working out that your boy just needed less power (and buying him a little green machine but I'm biased toward blue & green). And don't be disheartened if you don't get the response in the timeframe you want - it comes with time and not everyone feels comfortable posting ;)
Dave - waiting for daylight to stop? These kids just strap a torch to their bikes & carry on sometimes - run out of petrol is the one (or till an adult yells at them to stop lol).
