    I run some weedeater type motors in RC helicopters and NGK makes some plugs with iridium elements and they are by far the best I've used. Don't know the number for the plug in our bike engines, but I'm sure NGK would have a cross reference.

    If you take a look at the length of the stock plug with the head off (plug screwed in), you might be surprised. The stock plug is slightly too short. To correct this problem, try a NGK B6HS or ND W20FS-U plug. These are high quality plugs compared to the stock plug.

    My 50cc GenII Grubee Starfire came with a Chinese Z8C spark plug I found a cross reference table and the equivalents to it are:

    Chinese LD Z8C :
    N.G.K. C6HSA, G6M
    ENKER T70

    Here's a link to the table:

    best spark plug

    Hello from Spain, I bought my bike two weeks ago and I saw that de spark plug is very bad. I have changed the spark plug for this one: NGK BS7ES. This plug is suitable for piaggio and derbi mopeds and is the best for chinesse bike engines.
    I'm sorry for my little English.
