Anybody here?

So the 2013 Rotax Technical Regulations is out. Lots of changes.
Rotax Asia/Malaysia already announced to the banning of front brakes for Snr.

Any news/feedback on the carb side?

8.5 venturi only
min main jet size
float height spec (not given but i would assume 3/4mm)
Idle jets stamped 30, 35, 40, 45, 50, 55 and 60 are legal to be used
Idle emulsion tube stamped 30, 35, 40, 45, 50, 55 and 60 are legal to be used
It is not mandatory that idle emulsion tube and idle jet show the same size

Big changes I think..

Interesting rule changes.

The idle jets being open must've been done for a reason.. people drilling out the 30 for an in-between option?

Need to re-read the dellorto manual to prepare for next season

The minimum main jet size is up to the organizer - I don't think that will be put into effect in Malaysia/Asia.

Yes the regulations are on RotaxAsia.com and will be in effect starting at the Invitational on the 19-20th.

KZ knowledge will come in handy..
