Awesome! And yea I’m order a flywheel puller from treats. The flywheel has threads in the center of the hub. I tried using a 3 pronged puller I have. And surprisingly the flywheel wouldn’t budge. I have to re thread the center shaft a tiny bit cause it marred the end instead of popping the flywheel off.
Do you have any recommendations for CDIs? Everywhere I’m looking they seem to be specified for the Sachs 505, or are way to general to trust. I might just email treats and ask them.
