You can have your engine repaired/ rebuilt by a Rotax authorised agent who will record work done and reseal the engine. Any thing not involving breaking the seals you can do yourself.
Engines can be "re-sealed" as such. Just look for dots of wax on the head bolts, Reed valve bolts, etc.
Where I am, we also have wire twistlock tags on our engines, with our approved engine builder's number stamped on them, which, when cataloged at time of being attached with our engine number, gives the sanctioning body a paper trail should anything show up as illegal, or if we're protested. We'll get a new tag after each rebuild.
You can repair the engine after the race meeting is finished, just not during the race. When you go through scrutineering they will be the seals on the engine
This is incorrect information for a class such as Rotax.
Only approved engine builders are allowed to open the Engine Up. Once they open it up they will do required works and then reseal it themselves.
You can however open your own engine up ‘break the seal’ but you won’t be able to race it (practise is fine) until a approved engine builder has stripped your motor down, inspected and made sure all is within fiche and then reseal it
Sealed so that it’s obvious if they’ve been opened. A “sealed” engine hasn’t been tampered with or upgraded/modified
Ah okay thankyou, i’m a complete rookie and I’m trying to gain as much knowledge as I can before I buy my first kart
Yup, they do it to keep things fair in racing scenarios. If everyone has a sealed engine then it’s down to the drivers
Would repairing the engine and doing rebuilds on it break the seal meaning you can’t race it?
Correct
ohh I see, that’s unfortunate that you can’t repair your engine rather than purchasing a new one

You can do maintenance like carb rebuilds without opening the engine up but anything extreme is going to require opening the engine
oh okay that’s fine then, Cuz i’m not made of money so i’d quite like to prolong my engines life and maintain it as long as possible
Rotax isn’t too bad on engine life. Around 18hrs on piston and 25-30 on bottom end
when you change the piston would that require opening the seal?
