Extra heat protection:
To protect the bike I've put some aluminium tape on the inside of the fairing at the closest point to the exhaust and on the underside of the fuel tank. I've done this because the engine gets so hot I wanted to protect the fairing from melting, and it doesn't hurt to protect the fuel tank for the same reasons!
My cooling system tips:
When you run out of cooling liquid for your Mini Moto, use is distilled water which is available at your local garage, add some food colouring to it so that you can easily tell the level and away you go.
Only fill the reservoir to a quarter full, this is easily enough coolant and it leaves room for the pressure.
Once you have filled the coolant reservoir, there is often air locks in the system. To get rid of these start the bike and allow it to warm up, then bounce the bike (gently) on its back tyre with the bike vertical. Do this a few times, this should get rid of the air locks in the system and prevent overheating. The coolants level may need to be topped up now.
Gearing:
Changing the gearing on your mini moto is simple. A bigger front sprocket combined with a smaller rear sprocket creates a smaller ratio, this means that the mini moto will have better acceleration but less top speed. A smaller front sprocket with a bigger back sprocket will give your mini moto a better top speed but slower acceleration.
