Re: Can we ride in the rain?
Yes, but you'll get wet.
Take the advice given about sealing the magneto cover. You'll also want to assure that water can't get to the high voltage lead at the CDI. A silicone sealer will stop that.
If you have a rear fender that will keep water from entering the carburetor then you should be good to go. I've ridden in a Colorado downpour that would do justice to a Florida toad thumper and never had a misfire. Use common sense with speed and cornerning and you won't have any problems. Good luck, ride careful.
