reset your Heartgold game before getting to Johto? I'm thinking of restarting after the E4. I'm leaning towards Resetting but i dont wanna lose my Gengar Alakazam Feraligatr Meganium and Charizard. (Btw, I cant transfer pokemon so that's out.)
I think you meant, "getting to Kanto." After beating Lance, I just let the credits roll and proceed with the post-story line.
