In RMC Malaysia there has never been a problem with running an out-of-homologation kart.
If you check the regulations:
Quote:
Rotax Max – Senior Masters
(a) Chassis
Chassis must be CIK homologated or sanctioned by the authorised Rotax Distributor.
Maximum diameter of chassis tubing 32.0 mm, round tubing only. Rear axle maximum diameter: 50mm. Only 1 chassis allowed per driver.
So if the Rotax distributor agrees that the chassis can be raced then it is ok. There have been a few out of homologation and even non-homologated chassis that have raced in RMC Malaysia and Asia events.
As long as the chassis is in good condition it should be no problem. Brakes especially.
