125m performance

[125Mmadness]

What kind of performance parts can you get for a 125m (other than cam, carb, and exhaust) like pistons, valve springs, stroker kits, etc. as this is hypothetical and i do not plan to do these things as i just rebuit my 125 please don't tell me to just get a bigger bike.

Thanks but I've already done that. I'm wandering what kind of internal engine upgrades can be done. I have an nos rocky high comp piston in it now but, I would like to know what performance parts were made back in the day.
