[WC1]

Hi to everyone!! jsut wondering which ngk spark plug is best? i have a lifan 150 which came with a CR7hsa plug, i went to my local motor bike store to get a new one and the guy told me to get the CR6hsa instead, he said it was better for the Chinese engines, is this true or should i just stick to the CR7HSA, dose any one else use a ngk CR6HSA for there lifan 150??
cheers!

the 6 is a hotter plug than the 7. i run a 7 in all our pittys and in our race bikes and never have a problem. stick with the 7.
