If that is a regular occurance you require; http://www.nrcracing.com/covers.php
There is a member of this or the other forum that produces a very strong protection plate for the standard starter (peanut, to you lot) cover at a very reasonable price.(The OEM starter cover is the same on all 400/600 Fzr models, only difference is o shape on later models).
The topic was raised in the last few days regarding the protection plate.
