I have the sub tanks on my 02YZ250 and might trade it in for a 04YZ250F. I know they made the forks bigger, but could I squeeze them on or can I buy a different mount?
You may be able to have the new caps modified to acccept your tank lines.
I'd call Enzo and ask them what this would cost you. If it's mucho dinero, perhaps a local machine shop could oblige.
The tanks will work on any late model fork, you just need to be able to connect the tank lines to the fork caps at the bleed holes.
