Hey Hillbilly! Yes, as cross-country says above, the scrutineers have ways of checking the swept capacity of engines, should they be in any doubt - I imagine this is particularly important with bikes that share similar engines in a different capacity (such as the KTM EXC in 450 & 530 capacities for example). Of course usually the block (which is one of the components marked by the scrutineers) has the cc size cast into it, but that is not to say it might not have been over bored for example...
We would certainly be up-front about it, and indeed want
them to check it, just so there is no doubt in anyone's mind!
The idea is also to race the event on one engine, without ever having to take it out of the frame, so the original seals are all intact... just to show there is no funny business going on...
