I think that 2006 Yamaha YZF shrouds May be the right size / configuration / shape etc.
I attached some pictures - would be willing to purchase a shroud off eBay and send it to you to try.
Regarding the charger credit you can claim anything you put into it, materials you purchased, contractor costs, permit fees etc. - you could argue that the cost of the Alta charger should be included as well.
I used Turbo Tax and typed in the serial number and purchase price and it calculated the credit - I also filed for a home charging station and got 30% back in the install cost for the 240v outlet I installed for the bike.
Nice
I would really like to reduce the Regen to let the bike coast better - I think I could extend range by saving momentum - I think TCMB or Mark911 will soon crack the code so we can play with our settings (within reason) - I mess with my settings on my ebike depending on what I am doing with it -...
