Yes, a level 50 Raichu will need more exp points to level up then a pichu.

by trying to beat it
On at least level 50.
you should at LEAST be at level 50 to do it quite easily
level 50's (minimun level)
Have at least a level 60 or 50. I beat it with my level 67!
You first have to beat Story Mode. And to do that, you have to beat the final trainer in Stargazer Coluseum (I can't spell it) who is the Poketopia Master. I beat him using the Cool Boy with Haunter, Rotom, Mightyena, Sandslash, and two others I forgot. After you beat the Master, you can use Level 50 rule! (Or you can go to a Free Battle and set a custom rule to 50 All.
The level you need to be is level 50 or undefind (you can get level undefind if you have cheat engine)
I recomend Leveling a Pikachu to Level 50 first and then evolving it because then it will have learned all the moves Pikachu/Raichu can Learn. For Other Help Go To http://www.serebii.net/index2.shtml i did not make this site it just helps me out a lot.
