Of course, living where I do, do you think ANY auto parts store in town would have one? Oh no.... Back to Amazon....and then obviously I had to play the "free shipping on any order over 49.00" game (hooked on free shipping)....and it's just far too easy to find 41.00 more dollars worth of stuff I didn't need to buy... ;-) Hook, line and sinker, I tell ya.

Spark plug on carbureted version
Just four your information:
The spark plug that came with my RX3 2016 carbureted version is the DENSO U24ESR-NB, 0,7mm gap:

^^^ that spark plug is one step colder than the North American RX3.
Carburetor and the OCS are the only differences ? Wonder why we run a hotter plug ? It's the OCS and thermostat ? |

Replaced the DENSO U24 by NGK CR7
After looking at the comments here I´ve replaced the OEM DENSO U24ESR-NB with a NGK CR7EIX gapped at 0,75mm.
I´ll see how it performs.

^^^ be careful running that hotter plug wide open at low altitudes.
Get a good plug reading on an extended high speed run. I would stay with the 24 (8) unless you saw a dark(cold) plug. You always wanna stay with factory recommendations unless you have sufficient Evidence of running too "hot" or "cold" |

Why? I live at sea level in a very humid environment (if that matters, other than very dense, moist air) Every run on this bike is wide open throttle, that doesn't always equate to "high speed". I'm not sure what plug came in my US version bike, probably the same as all the other FI models sold here. Could it be an issue? |

Would be wide open at sea level (as lean as you would get) The only reason to stray from factory recommended heat range would be: If you just road around town and at slow speeds you might go 1 step hotter. Or running long distance wide open then go with 1 step colder range. Many Jap bikes will recommend just that in their manuals."For continuous high speed running" Strangely Zongshen(at least in North America)runs a 7 heat range when jap road Bikes run 8's. (NGK heat range reference numbers). NGK 7 and 8= ND 22 and 24 It is safe to say that heat range selection is not as critical with FI compared to carbs. If you select a too cold a plug no big deal but it is a big deal if you select too hot a plug. Last edited by Inroads; 12-25-2016 at 11:23 PM. |

You would have to have a fair amount of carbon to create a hot spot/knock. Not gonna happen with one step colder. There are no knock sensors/retard on these bikes. |

I would possibly consider 1 step colder on extended high speed long distance runs. It wouldn't hurt. In addition you should be reading your plug. |
