Size should be the same, but '87 lists 8 different carb assemblies. These varied based on engine serial numbers. Not sure what the differences were. I bet any would work, but may (will) have to be jetted properly.

89 Carbs are a larger diameter. Going to the 87 carbs will give you less airflow.

New motor problems. Or maybe even the carbs?
