I just came across the following sentence (which can be found here);
Had I better go with you?
I think, that is correct; I just don't know what the context/meaning would be!
Amazingly, Google-ngrams found the frequencies of only the original one.
Should there be a past-participle used, eg;
Had I better gone with you? (This one makes no sense to me either!)
Is there any other (better) way of expressing the POV of the actual sentence?
