Also, 50amp on lyen sounds good to me, I use 50amp too and motor won't get warm at all while doing 5min WOT! But controller do get hot so you wouldn't want to do 20min of WOT....:p
It looks modified to me but then I have not seen unmodified ones so I'm not 100% sure
Is that a 12 fet controller you're using that gets hot? Would an 18 Fet controller be more appropriate for full throttle for 15 to 20 minutes? Your top speed sounds pretty good to me. I don't know how often I'll actually be riding at max speed but it will certainly be nice to have it and be able to sustain it for 15 to 20 minutes.
