In case you're not aware you should be looking for ZR600 EFI parts. Not may shops will list them as ZL specific parts.
Also, before buying be sure to confirm that your choice of fart can will fit your reverse/Elec. start. Some cans only fit the stock (non-reverse) chaincase. The reverse chaincase cover is larger.
Here are links to some suppliers of AC Hi-Po parts. If ZL not listed search for ZR600 EFI items.
