I have all of the corrected Air/Fuel data needed to get Sport/Daytona/Centauro bikes running well, stock EPROM or others (as I can burn EPROMs as well) via this; https://www.guzzitech.com/store/product/power-commander-pciii/ - if you chat with Will, he used to say his chip works well in conjunction with the PC.
For carb or injected bikes, be sure you store your bikes with non-ethanol fuels or better yet, aviation fuel. Super stable long term. My $.02.
