30hp from an aircooled 125 is impressive to the point of being complete bullshit... :)

I have an 80cc kit as well that's going on a YZ80C.   Theres always those cylinders for the 125's for sale a evilbay.....99% of the time they need rechroming and the nicosil we have these days is not compatable with the old chrome style rings.

I noticed that the hp curve was better all of the through, looked very sus because when we see real dyno tests once mods are performed before and after generally they do not increase and follow the same curve.
I have a soft spot japanese mxers with aluminium tanks. Two stroke classic Dirt Track...

The horses are smaller in Japan so you need 2 of theirs to make one of ours.

Part of it is Japanese always measure at the crank, Europe it's at the sprocket and everywhere else at the wheel.
