Would you wait to power up 98% Raikou?
I was super lucky to catch a 98% 1906 Raikou on first and only raid today. My first impression is to use rare candies to either power to level 30 or max to my level 37, than I thought that would suck to catch 100% even though realistically it means nothing it's more psychological. It happen with Moltres caught 96% and 2 days later caught 100% especially since around for month and I'll continue to raid Raikou obviously. Should I wait until weekend ends? End of month? Or power him up?

I assume this Raikou has a 14 attack IV, because my 98% Raikou is CP 1909 (15A/14D/15S). A 100% IV Raikou would be a little better than the one you have now, as would a 98% with a 15 attack IV, and arguably even a 96% with a 15 attack IV.
You've got a great pokemon there, but if you are going to continue to raid Raikou, there is a reasonable chance of getting a better one, so I see no reason not to wait until the end of the month.
It was my third try to catch a Raikou. My first had CP 1913 (i.e. 100% IV's), and I failed to catch it. The second was around 1870, and my heart wasn't really in it, after losing the perfect specimen, and I failed again. I was very happy to get the 1909 on the third try.
Other than that, I have a 91% Articuno, and all of my other legendaries (out of 11 total) are 82% or lower.
