Best Spark Plug?

cruiserdude · #1 03-13-2009, 07:47 PM

i have a 2 stroke 48cc engine, the model is Starfire Gen II . I would like to get a performance Spark plug rather then my original plug. What should i be looking for to make sure its the correct plug? Does it just have to be for 50cc motors or does a specific size, model etc matter?

I suggest NGK BP5HS or BP6HS. Both have extended tips.

The 49cc and 67cc all use the same basic plug size.

I like NGK & Bosch plugs... your local auto parts store can cross reference a bosch from the NGK #.

I got the NGK BP6hs for 1.99 since eveyone is talking about them! I figure thats the best performance one but for the price you wouldnt think that. They dont have Iridium plugs for 50cc motors? that would make a bike real fast.

There is an Iridium equivalent, I believe it's BR6HIX. But it is about $6-$7 and I doubt it will buy much.

best spark plug to me is one that is cheap and works champion L78C or the china until it craps the bed then it takes a dirt nap.

so you suggest i replace the stock plug with the NGK BP6hs and not even bother paying for the iridium plug?

now i wanted to know whether i should get an upgarded CDI with my NGK BP6hs plug or not? Will i notice the difference even on my stock CDI?

I run a ngk as well, i tried a bosch +4. No big difference, from the single electrode.

If you use the stock CDI with a Iridium IX (BPR6HIX), It will be a VERY noticeable improvement over a standard plug.

The engine has a slightly higher Idle RPM and doesn't misfire as much. If you ask me, it's worth the money because the plugs have a longer service life than the standard plugs, they won't foul up easily either, which means easier starts. Give it a shot and let us know what you think.
