New Bike Hesitating / Sputtering

[ClassicVW_imp]

Why does it take the dealer so long to get plugs? Are we using some crazy special plug of some kind, I don't think it would be an issue to just get some plugs. Even if he didn't stock them, they can be over night ed from anywhere in US. How long has this been going on, any updates. I would definetely think it would be taken care of by now.

Yes. The stock plug is an NGK oddball with a very long nose. I haven't seen any other bikes that use it in the cross-reference charts, nor have I seen a compatible version made by another company.

Doesn't explain why it is taking this dealer so long to get them. Just that this plug is not like a standard NGK or ND plug that are commonly stocked.

Well that sucks, why would Honda go out and use such odd ball parts that it becomes an issue to obtain them especially something as simple as plugs. I'm already worried about replacing tires down the road in the future with the odd ball tire sizes. What do you do 5 to 10 years down the line when this bike is just a thing of the past and nobody uses these tire sizes anymore? They should have standardized alot of things.

I believe they went with the long nose plugs for better heat dissipation on the cylinder head.

I'd stick with NGK IMHO. I run D8EA's in my 915 kit with Andrews performance ignition coils and wires, 0 issues.

Genuine part # Honda - 31908-MGC-003 - S/PLG (LMAR8A-9S)
(All I could find on it)

xNE0x, I don't think those plugs that Bike Bandit lists are really compatible. It looks like just a general list of motorcycle plugs that they think might fit a CB11. When in doubt, you can tell an NGK LMAR8A type because the threaded portion is about as long as the ceramic insulator.

So far, Denso and Champion haven't listed a compatible plug in their cross reference charts. NGK doesn't even list an iridium or platinum version. It's a real oddball. (and it seems to be priced accordingly )

Even though I'm not paying for the plugs (Honda is), I asked him about them. Don't know the exact price but the Service Manager said they're about 20 bucks a piece. So $80 for 4 plugs!! WOW.

I guess it's been awhile since I shopped for Honda Motorcycle parts . . . .

Still not as bad as BMW's prices!

Well at least the plugs today usually are good for at least 100k in cars so I'm sure the bike ones will last at least half that if not more so changing them should be few and far between unless you have a problem.

i just bought a set of plugs from Babbits Honda, $14.56 each but shipping is a bit exp. total for all 58.24 plus shipping Total 74.39 These are tough to find, tried my wholesaler, he said they where unavailable so i figured in a emergency I better have a set.

Any news OP?

Ethanol gas goes bad VERY quickly. Sometimes it already has moisture in it out of the pump which will then separate and end up at the bottom of the tank, then getting pulled into the motor by the injectors. Water does not burn, so there's the hesitation. It could be electrical but that's hard to imagine. The assembly line is so A to B to C. If it was haphazard they would have these issues ALL the time. Only my old two strokes fouled plugs. But I can imagine a dealer or previous owner putting in Gas Can Gas. That would do it. If it runs smooth at 35 mph for example, I'd just ride a back road for a while and/or syphon the gas out of the tank.

Trey, any resolutions????

I reckon the fuel would be long spent by now, or incredibly "waxy".

I use Chevron Techron fuel system cleaner. I have cleaned a clogged injector on a car with it. 1-1/2 ounces per gallon of gas

I also use the Techron fuel stabilizer along with seafoam. Both good products , and always use 91 octane ethanol free fuel. Never have had fueling issues in multiple small engines.
