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 !!

:LOL:

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.

plug

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

Comments: hi, i moderate a forum called www.motoredbikes.com and we have
a coupla questions if you don't mind trying to help.

we use 2-stroke engines manufactured in china. 48cc and 70cc for the
most part.

2 aftermarket plugs that we use are the b6hs and the b7hs, but we don't
know *why* we use them, it was suggested is all.

could you recommend a suitable non-resistor spark plug? also, what gap
should we be using?

thanks very much.

Hello,

Both the B6HS and B7HS are non resistor spark plugs. There is a heat
range difference between these two plugs, 6 is hotter and 7 is cooler.
The engine manufacturers will specify the correct plug to use based on
their engineering findings. This will also determine what gap to set
the spark plugs to. For more information and details, I would need to
know more about the machines the spark plugs are used in. Thank you.

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.
