Hi Ryan,
Not necessarily...we will not fail bikes due to lack of availability of race covers for that particular bike. We certainly don't want to discourage anyone from racing in EMRA events(quite the contrary), however...
We are trying to be flexible about the new rule requirement, while ensuring that the intent of the rule is met(i.e. bikes must not be deemed to be at elevated risk of oiling the track in the event of a crash).
Please have a read of this post....it should help to answer your questions.

Hope that helps.
If you have any more specific questions, please post up or send me a PM.
Thanks,
Juan
