Bahahaaaa!! I feel for you brother, we're 78 &partly cloudy today. But to be honest, she doesn't roar, it's more of a agricultural cacophony. Don't get me wrong, I love the sound, but it's an acquired taste.
Ahahah! Yeah!
Was just diverting the conversation!

78 Fahrenheit?!
What about -4F!! That’s awfull!

About the sound of S10 ...is that sound cured with the sec gen!?

-4F, :eek:. No thank you. I didn't consider the sound a "problem". So, no, the sound is the same. I thought you were talking about the fueling and CCH. "I" consider the Tenere "refined"; but that's just my opinion.

No No ! Was just joking about the sound ..just to stay in the subject of the post!

:rolleyes: Rust in the spark plug wells, note that the left, downhill side if you part on the side stand all the time, is the most corroded. Sorry to those that have experienced it, but that's just lack of owner maintenance. Ignore any mechanical device long enough and you'll have some problems. In wet climates, you simply need to check that area more. A little dielectric grease and some silicone RTV around the head of the coil stick will prevent a lot of headaches later..
Agreed all bikes have problems but take offence at "lack of owner maintenance" bike reglurary serviced, centre stand used 99% of the time and the ONLY bike I have owned in 44 years that has had rusted in spark plugs!
Someone at work has had it happen to her car ffs! Stick coils hmm!
Loved the bike and a damn site less problems with it than 2 previous BMW's but don't blame a design flaw on a lack of maintenance!

I agree with you that it's a design fail. But if you know about the issue, it's just a matter of going in there more often to clean/tidy. Ever spray ACF50 in the spark plug wells after changing or cleaning plugs? Most just spray it on the outside.

IMHO, the rust comes more from water sitting in the plug wells than just residual moisture. There should be enough engine heat to bake out any residual moisture. A light ring of RTV around the top where the coil mates to the valve cover with some dielectric grease on the plug ceramic would likely prevent most of the corrosion.

But yes, the front tire spray goes right at the front of the engine where the stick coils are. Sucky design. Some type of spray deflector might do wonders for this issue.

Probably Yamaha does not get the claim of the rust in spark. However i read in this and another forum, the complaint made to yamaha about breakage in the rear ring. Yamaha solved it with “stronger”2019 ring. The claim does not have to be in the forum, have to get to the factory’s ears
If someone proposed that each of us send a email to Yamaha, complainig about spark rust, I would participate in the shipment

But, considering his location, the poor thing probably hardly ever gets to dry out. Kinda like the t-shirt I saw in Seattle...."people in Seattle don't tan, they rust".

I've been to Seattle, (many times),.... Grey! Lived in Portland for 45 years and it's not as grey as Seattle. Never been to England though. Island life, eh? More salt air and more wet. Thus the attention to ACF-50, a great product, but maybe needing to be sprayed into the spark plug wells?

I don't know how hot it gets down in the plug wells, but my guess is that it's plenty warm enough to evaporate any moisture in there while the engine is running. The trouble probably starts when you park the bike and there's still water in the plug well, especially if the bike is going to sit for a few days. The cap on the coil stick slows down the evaporation when the engine cools off, and the plug might sit there for a few days submerged in water. I imagine that doesn't have to occur too many times for the plugs to get massively corroded like those I've seen in some photos on this forum, especially if there's road salt mixed in with the water. The trouble with relying on the maintenance schedule when you check the plugs is that, if you wait 4000 miles between checking them, you might still be giving a submerged plug lots of time to get rusty, even though you're diligent in conducting maintenance on schedule. The biggest preventative measure is trying to keep the water out of there in the first place. Even a splash guard, though it could help, may still not totally prevent water from getting on top the cylinder head, and once it's there, it can still work its way down into the plug well. I've had success so far with making a grease seal on the underside of the cap on the coil stick where it makes contact with the plug well, or at least it seems like success since I haven't had the problem occur. The seal may have leaked since I last pulled the plugs though, and my plugs might look like they have barnacles on them by now.

I believe there's a thread on here where a member removed the metal sheaths on the outside of the coil sticks, and that eliminated part of the problem. I suppose the metal sheaths are there to give the coil stick some rigidity so you can push it onto the spark plug, so I don't know if losing the sheath affects that or not.

Alternately, you could just let the engine idle when you get back from a ride when it's been raining. 10 minutes of idling where the engine is running between 205 and 220 degrees might be enough to boil off whatever water might have gotten inside the plug wells.

I didn't have any ACF50 last time I did my plugs. I did wipe the exposed metal parts of them with WD-40. No idea if that'll make any difference or not.

exactly, bad design by yamaha, not for the first time BTW.
It must be very hard for engineers to foresee a water will be coming on that place LOL,
students could do better. Yet they remove fender extender just to save few bucks,
regardless all of older bikes had it for a reason.

You may well have been joking about the sound, but the clutch in the Gen 2 is definitely quieter than that of the Gen 1 bike.

The latter bike is quieter, less clattery.

Yes, no other manufacturer ever got a design wrong...

Yes, the engineers thought that the coil stick seals would have been sufficient. Sadly not. I'm also sure that plenty of students could have done worse too.

So let's get this right. The manufacturer designs a mudguard that's too short on purpose, fits a fender extender from the factory (rather than just make it longer in the first place), then to save a few quid they stop fitting it? Really?

Oh, fender extenders are made for other brands of bikes too because they are all too short.

Rather than wasting your life trolling a bike you don't even own (and looking at your trolling, are ever likely to own) why don't you offer your engineering expertise to all the manufacturers? I'm sure they would love to have a very knowledgeable troll on the payroll. Start with advising on emissions systems and progress from there. You'll be designing coil sticks by the end of the week...

I love the sound of that bike.
Will probably stick a pipe in the future. Just like louder grunt .Personnal opinion.

If I look back at previous post It may be interpreted the wrong way. Sorry for that.
And maybe because I’m mostly write and speak french 99,999% of the time and maybe because I’m writing in a clumsy english. Sorry for that.

Yeah, it’s almost as bad as designing a motor with the heads exposed and laying in front of your shins. SMH

Been riding the bike for 20k km now with the O-rings with no sign of water in plug wells. O-rings are the fix. I rode through multiple tropical downpours and the O-rings do hold up.

Thanks for the link to that thread.

Ahhhh….the perfect motorcycle, that's the one I want. I forgot, who makes it? Oh yeah, that's right....nobody. A productive member of this forum will come across a problem/imperfection, and then inquire to, or advise of, a solution to the imperfection. Some just bitch about why the bike sucks, without any desire ,or intent, to solve the alleged problem/imperfection. Others, like me, take the bike as is and work around or ignore any issues that arise; because, in my opinion, Japan doesn't build a crappy bike. Probably why so many of us here have different style/types of bikes. Different shoes for different dances.

It rains 60" a year here in Ms. Seattle gets 38" and they whine about rain. I put a fender extender on my 13 when it had about 800 miles on it after riding it down a loggin road and seeing that mess. My sparkplug wells still look shiny inside. I have to push hard on the plug coils to gettem to go all the way down. I can feel them click
