If you're using a flywheel from an engine with a 12 volt starter, you're also going to have to replace the starter drive gear. So far as the throwout bearing adjustment goes, you're probably going to have to install the TO bearing with the longer dimension from the fork to the bearing face. Unless you have a reason to need the heavy duty clutch, it's just creating more work, and a parts chasing nightmare for the next guy who buys clutch parts for that rig.
