If the boot that connects the air box to the carb not all the way onto the air box cause a lean condition . I just did the head gasket mod on my 97 600 and found the exhaust side of the pto side piston burnt off . I replaced the piston and cleaned the carbs but found nothing wrong . Last winter it was backfiring and didn't want to run thatwas when I found that boot off center . that was the only thing I foud wrong that day to.
