my thoughts on the posted concepts:

'The 200s will always be equal...'

# nope, never been achieved in any formula I have ever come across. Close performance maybe but equal... never!

'The 200s are equalised by adjusting the ignition timing and then sealed in 4 places - crank cover, flywheel cover, head and carb'.

# all sealing does is cost the diyer.If you know anything about the Gx engines you will know how the valves need keeping on top of for best performance. It's as daft as paying for a rotax dealer to change a piston ring

-and as for seals being inpenetrable... not for long, again ask rotax owners how they feel about the seal!

Once your engine needs to be retuned to be serviced, RPM will reset the power and torque outputs back to the original figure, lets call it 7.1hp. Even if, once rebuilt, this engine produces 6.5hp or 8.5hp it will be adjusted so that when it leaves RPM is is back to 7.1hp - equal with every other engine.
# see below + quoting a figure is pointless when it's the area under the curve that decides the usefulness of an engine on the track.

For certain events Roger will have his portable dyno for anyone who wishes to question a competitors engine. If the engine produces too much power they are DSQ, simple.
# here's the facts... Roger's workshop dyno cost many times more than his travelling dyno.
So... if an engine is set up on the workshop dyno, when first built for sale and then checked on the travelling dyno, the readings may well differ.
If this difference causes a DSQ then you may feel badly treated.

So... any more series concepts for debate?
