I have it. It says
1. Cilindro en aluminio Niquel+Silicio
2. Part number: HR4000221MR-2
3. Squish: 0,5-0,7mm
4. Spark Plug: B10EGV
I calle Hebo and the said that the piston is now silicone & it is 1mm shorter, everything else is pretty much the same. If you need anything else, please do not hesitate to ask.

I know on racing ZIP-s they do not mount the thermostat. This is ok if the bike is used for racing, because almost all of the race the engine is at full power, so the temperature is more or less constant.
Personally, on a scoot racing tuned for road use, I would mount a thermostat that keeps the temperature around 60°C. Temperature fluctuations surely ain't good.
Does that gokart thermostat fit on scooters?

No, don't mount the stock thermostat. I think they open at too high temp. Racing cylinders are made (tollerances) to run at lower temps because an cooler engine makes higher power.
I guess it is possible to modify the stock thermostat so it would open at lower temp (softer spring?).
Don't mount the gokart thermostat too if it doesn't fit in the place where the original does, because it has to be as closer to the cylinder as possible. Well, don't know how an gokart thermostat works.

Yes, I know how the thermostat works.
But if you mount the thermostat far away from the cylinder, it wont respond quickly to a sharp rise of cylinder temperature. I guess you know what this means...

But I can fit it near to the head, it's not to much differences (approx. 7-8 cm)! And this method works for gokarts too!

Browni what brand of waterpump are you using. you can use the electric waterpump and it wont rob your engine of power. on the electric pump you can also turn it on and off with a toggle switch when the temp raises from being at a stop for too long. i have a honda elite with a 121 stroker motor that is watercooled and it just let the electic pump stay on and the bike never over heats.
