hi I have a 2002 cbr600f f4i and have just done a new oil change oil cooler and exhust rings. just filling up the coolant with castrol coolant an I noticed a small print on the bottle saying do not use with magnesium alloy. I am now worried I have the wrong coolant in as some say it can cause damage. can anyone tell me if I need to drain it again or will it be OK. any help be great. ok thanks

 

Doubt there's any magnesium in bike, so you're fine.

More important is to never ever mix coolant types. Mixture will turn to gel and clog up entire cooling system.
