Just fitted my new CEN NT 16 engine , to my pure ten alpha .
I am trying to break in the engine at the moment , however I am having trouble with it overheating .
So far I have not been able to run a single tank without it overheating
I have got at most , through half a tank , then I do the spit test and its way too hot and I have to shut it off and cool it down .
Ive tried opening out the needle to make it richer , however this hasn't worked . My air filter is clean , and letting air in so thats not the problem .
Anyone got any ideas
