As long as the outputs are within spec according to Suzuki, you should be fine. Confirm with a volt meter to be sure, it should take ten minutes tops.
I'm running one off of a newer GS500 for two years now and things are fine.
I'd almost say that may be more of a case of jetting for your hesitation. When my RR went, operation was fine, it was starting and stopping that was the big issue.
