Protecting coils, dialectric grease etc.

[semmyroundel]

My questions refer to the protection against water ingress from the front wheel...the bike was bought secondhand 2018 ZE model 6000 miles from new.
I've ridden the bike a day after being on rainy roads and it cut out twice the following day, my local Yamaha dealer pointed the finger firmly at the coils/spark plugs. I have an extended warranty, so hopefully they'll take up the baton to carry out the work, if not, I'll do it myself.
1. Where EXACTLY should the dialectric grease go when replacing plugs and coils, in the case that the insurance don't do the work? (I am planning to fit NGK titanium, unless you say why I shouldn't).
2. What detrimental effect (if any at all) does putting a plate in front of the affected area with regard to cooling air, to prevent water hitting coil/plugs area? Some have mentioned an old license plate.
3. Who does a decent deflector that could be added to the bottom of the front fender (mudguard)? I'm in the UK, so european places only please.
TIA

This fender extender is easy to fit and makes a huge improvement in reducing the amount of spray and road debris getting on top of the engine. I’ve had my coils/plugs out twice since fitting it and have not noticed anymore water ingress. I run the standard small plastic skid plate thingy and have no issues with extender/plate contact. Note, I do not do any off-road riding.

If you search my posts, there are pics of the extender fitted.

Thanks Boris, much appreciated.
Reading through the exclusions on my insurance policy, it mentions spark plugs and caps. I wonder whether a "cap" is the same as the coils that are caps as well, I'll have to find out whether they'll wear that, because they also exclude corrosion..
I would be surprised if the coils had broken down in such a short space of time (mileage).

Found a pic………..this is, or is very similar to a Super Tenere coil. If I were using dielectric grease, the two arrows are where I’d place it. The bottom arrow seals where the cap meets the valve cover, I’m not sure if it’d just burn off. My suspicion is that the top seal is where water gets in.

Dielectric grease (also known as silicon grease) is great for keeping rubber supple and water proofing. If you haven’t got any, get some. But I also use a spray contact cleaner by WD. It does a great job of cleaning off corrosion on the actual contacts

I rode through torrential rains for 600 miles in Canada, the water sprayed up onto the top of the engine and got into the spark plug wells and also filled my air box with water. The bike was running pretty bad. I had to remove the tank and the air box, dry everything out as best I could and put it all back together.

If I remember correctly, I put dielectric grease on the inside of the boots and even ran a bit of high temp sealant around the upper sealing area of them. I ordered a fender extender and have been running that ever since, but haven't had to ride through such heavy rain for such a long time as that after I have installed it. Some people have had disastrous results with the fender extender hitting their skid plate during hard off road riding, which causes the front fender to break. I have ridden a fair amount of off road with my bike since the install and have had no such issues, but who knows.

The top arrow wouldn't be a leaker. The bottom arrow could use a smear of silicon grease. Another addition folks have done is to add an o-ring into the area of the bottom arrow along with the grease. Part of the front motor mount covers that front empty space.

Quite a few of us have fitted an old uk licence plate to reduce spray further, it doesn't seem to have any impact on cooling. There is another thread on this somewhere.

Yoyo, is that a Givi set of crash bars I can see? How did you slip the plate up there and attach it? I don't keep the bike at my house so I can't pop out as I write to go and have a look

I'm in the UK my bike is also a 2018, I have added an extender then a £2 mud flap, I have the oem raid bash plate and have had no clashes, can ride in appaling torential rain with no ingress of water, I have had no problems off road with this either, some times simple is good

 

[semmyroundel]

Cheers for posting the pics, I can see how that will work.
I have a Givi skid plate that's not too different to yours.
Loving the blacked out look, mine is Baltic blue, so I've had to resort to a Bagster in black to black it up (it's a late 2017 registered in 2018)

 

[Superraid]

Any pictures, haven't seen anyone in the UK on one since I bought mine new in 2018, the last year hasn't helped alot only managed to get up to 15k miles since I got it

 

[bimota]

yep uk plate

 

[semmyroundel]

Sorry is not a better picture, anyway main reason I liked it apart from colour is black forks. I knew I would get a bagster eventually

 

[Superraid]

Cool, if you ever head north give me a shout,I'm up round leicester
