    also forgot to ask what is the correct plug gap for the 48 cc chinese engines using ngk b7hs plugs

    i just bought a b6hs, i was told, but haven't been able to confirm, that's it's non-resistor.

    well went to the ngk website and in the # on the plug if it has a R in the letters its a resistor type thats sorta what i got out of the reading there so b6hs or b7hs according to what i read is a non-resitor type but i dont really know there is no R in the ## so im guessing it is a non-resistor type haha!!! anybody really know there plug shi# let us know !!

    i just got back from the ngk site...i also knew that "r" is supposed to indicate resistor, but to doublecheck i submitted the contact form, described our engines, and asked for recommendations & advice.

    i'll post whatever they send me :)

    oh here it is on the grubee site

    Remove spark plug and inspect for excess carbon build up. Clean, re-gap to .028- .034 of an inch if necessary. Check plug after every 20 hours of operation. New spark plugs are available from your selling dealer. Be careful using aftermarket spark plugs as heat range and threads differ greatly. Extra plug is included with kit.

    On one of the other sites we talked about plugs last yr. the general concensis was to gap at .03 and so far I have only worn out 2 plugs the one that came with the kit and one I bought to replace that one had to buy another one this yrae the bike was getting hard to start .... but hay over 3000 miles a plug has the right to say ENOUGH!! lol

    hey, hiya cookie...thanks for that :)

    while i did put "bicycle" in "vehicle type" & included a link to MBc, it seems they need to know more...but he did give a bit of helpful info.

    You got it right, hard to believe a non-resistor plug can cause a electrical interference with radio and television. All resistor plugs have a "R" non-resistor plug dont. You dont want to use a resistor plug and a non-resistor plug wire. As far as I know they dont make non-resistor wire anymore, but what comes from China who knows? As a kid, I always thought the "R" was for resisting oil foul, boy was I shocked. I used to work at a parts store right out of high school. I was sent to Champion as a representive to keep their account, that's what they told me.
