You can find entry forms on the
main page of the kartmore rotax site, on the
regulations page of the kartmore racing site, it has been posted on the main page of KartingAsia.com, and it should've been emailed to all competitors.
The entry form for Malaysia Max is the same as it has been all year and can also be used, and is also available on the Rotax Regulations page.
Just to clarify: the entry fee is RM350 for Asia Max. If you're a Malaysian/Singaporean competitor you can enter only the Malaysia Max for RM250, and won't score points in the Asia Max. For RM350 you are entered in both.
If you're not receiving any emails let me know and I'll make sure you go on the list.
