if your bike / engine is near new you must not over rev the engine until atleast 4 tank fulls of fuel has been used. also you should be using a good quality 2 stroke oil mixed at a 25 to 1 ratio just the same as the motor mower mix. when your engine is run in it wont get nearly as hot.

[mac90]

make sure your fuel oil mix is 25:1 & you have good airflow

inspect flywheel & pull starter shroud to make sure it directing air over the head
if your engine still has the plastic cover you can remove it

it will aslo heat up more during run in as the engine tolerances are tighter & can create more friction this is why its important to run a full synthetic 2 stroke oil at 25:1 ratio

& try not to let the bike idle too long if it gets hot give it time to cool down before next ride
