    So, I've always used NGK B5, B6 plugs on my 66cc with very good luck. I'm hearing now that if you think those NGK's are good, then try the E3 plug. Does anyone know if this is true?

    I wonder if the three prong would give you better power with more over-all firing?

    Wow, I've never heard about the BR9? Uno, that's quite a bit of miles for these little engines. All I've heard of is B5,B6, and B7 NGK. So, can you tell me how you ride in order to be that successful with miles. See, I'm right at 650 original miles, and from what I've read, that's pretty good considering all original.

    Uno, if the B9 plug has helped, I'll try to find one today!!!!!!!!!!~

    Glen (So, were those miles all with original CDI?) See, I bought Jags new performance CDI to help save bearings.

    Doesn't the "R" designation make it a resistor plug and the "9" make it a very cold plug.
    Forgive me for not doing my research, but i've found that the projector nose NGK plugs to work quite well. I am currently using an NGK BP6HS - non resistor plug.

    Fabian, uno there's got to be more to it than just the BR9 NGK plug that your using to get that kind of miles from a "China Wonder?" I believe you Thearc, but that's pretty impressive. Tell me, how did you put those miles on bike? Where? Mix ratio?

    Fabian, Yes, higher number cooler plug.........................

    LOL cool people, the trick,I ride 36 miles round trip 5 days a week lost the top end at 2200 or so miles needle bearing , new top end piston, rings,found a cyl, with a 40mm intake, and chrome slant head, run cns high performance carb, with a big air cleaner the ones that come stock are junk and run a MM hub and sprocket with a 40 tooth, top end is 34.6 mph, gas is 32:1, try a UNI air filter, FUN RIDE!!!have 3318 miles on bottom end, Have a bro that put 4200 plus on his 48CC

    E3 plugs are great for slant heads, they're meant to increase and spread the spark more evenly across the top of the piston. I have used both the NGK and E3 type plug.. E3 seems to work best on my setup.

    Is it not possible that slant heads were designed out of packaging requirements; enabling the engine to fit into compact (space restricted) bicycle frames. Higher compression is a function of the design.
    I have yet to see a high performance 2-stroke engine with a canted (off centre) spark plug.

    DEATH, for 2/stroke!!!!!!!!!!!!!!!!!!!!!!!

    If someone is prepared to give me a large sum of money, i am quite happy to design a direct injection, multi-fuel, compression ignition 2-stroke bicycle engine.

    This will eliminate the need to make a stressful and vexing decision on spark plug choice.

    E3.12 plug

    Ok, I've also got the new JNmotors CDI. It comes with a chrome spark plug boot that I just wonder will fit, considering the E3.12 plug is shorter???

    I've always used NGK, but as you can see, the E3 plug is a bit shorter?

    Does anyone know?
