I have been using the Z80 stock motors. What size NGK plug should I use for a stock motor? The climate here in Delaware is Hot summers and cold winters right in the middle. I just need alittle hotter plug than the stock plugs that are offered on the sites

NGK BR6HS or B6HS. The R = resistor type, not necessary according to some folks, but I always run a resistor type with CDI ignitions and recommend their use with CDI ignitions.
FYI, the stock heat range would be a "7".

I do concur with DD94... a NGK #7 is a colder plug & a good choice for 'Wide Open Throttle' riding in extreme desert heat.
The summers here in So-Cal aren't really that hot. :/

I will say this about the B7HS: GREAT PLUG in the hot, or if you're running that engine HARD like I do.

However, it's a bear in the cold; it takes FOREVER to warm up under 70 degrees it seems.
