water in front plug

[01 sv650s]

i was going along the motorway today in the rain and my curvy started to misfire. when i got to collage i found out that it had water in the front plug cap. is there anything i can do to stop this from happening again

[hovis]

dont go out in the rain :wink:

have you got a fender extender? as this will help

[Biker Biggles]

Fenda extender,silicone sealant over the plug hole cover,and make sure the drain hole from the plug hole is clear.

[hovis]

make sure the drain hole from the plug hole is clear.

:shock: drain hole ?

[kwak zzr]

ive never had this problem? i wonder why :oops: :oops: :oops:

[northwind]

Silicon goop from Maplins... Part number RE90X, costs £3.73 for the 50g tube and it'll do you for the life of the bike. It's basically a 100% cure. Slight pain to do the first time, thereafter you just do it whenever you change plugs- all it takes is a generous smear around the cap. Honestly the best £3.73 you'll ever spend on an all-weather bike, IMO.

Both cylinders have a drain hole.On the front it exits on the off side of the cylinder head just below where the tip of the plug would be when screwed in position.Poke it with a bit of thin wire and spray some WD40 up it. :oops:

Hello
Same problem here
I already have the fenda, I'll buy the silicone tomorrow.
Is there anything else that can/should be done to solve this?
Cheers

Not really either of the two will do the job! Me personally would go with the silicone greace I don't like fender extenders I had one come off and shatter my front mudguard fortunetly it didn't lock the front wheel up! And they look crap!

Welcome to the forum;)

[chazzyb]

I havn't had a problem since I fitted a fenda-extender. And it stops crap flying up over the front pot. Oh, is that why it works then? ;)

[dyzio]

Thanks for the instant reply
Think I'll try to do both tomorrow, just to be sure, would hate to stop on the motorway again :mad:

Fenda extender,silicone sealant over the plug hole cover,and make sure the drain hole from the plug hole is clear.

This should not be necessary (except cleaning the drain hole) if the cap is correctly orientated. IIRC the correct orientation of the plug caps is described in the workshop manual. I haven't had a single misfire since I started paying attention to this, and I live in one of the most rainy places in Europe ;-)

Not every SV has this problem, but with my luck...](*,) I just had to pick out one that has it ...
I'll install the extenda tomorrow, and replace the plugs the plugs & silicone the caps next month (service)

[dyzio]

Everything was ok until last weekend...
Went to Glasgow and had 1 or 2 missfires, left the bike uncovered for the night.
Next day when trying to start it, the first cylinder didn't work... (it was p**** rain all night and day), a quick procedure with wd40 did the trick and everything started working ok.
I have a fenda extenda, but no silicone on the spark plug cap.
What could be the solution?
New HT lead, spark plug cap or just to put silicone around it??

I agree. I got a powerbronze and a pyramid EF in my garage, just cannot bring meself to drill holes just to fit such bad looking things on.. Oh . and I tested most adhesives the guys suggested - none are secure. Just pull them after you stick them .. They
will come off..

It shouldn't be, but the cap doesn't always do the job... I even replaced mine with a new one, no luck, which is why I turned to the grease. It's a 100% fix and costs practically nothing, so there's nothing much to lose really. I've crossed about 40 metres of floods up past my toes without so much as a blip (though I regretted it once my feet got wet :rolleyes:)

What Northy said. Twice. :D

I was getting what I presume must've been this at the weekend, riding up to Edinburgh in the rain, bike was running really 'lumpy' at around 4000rpm, but perfect again the next day (in the dry). Is it just a case of removing the front Spark Plug & giving it a good dollop of silicon grease round where it seals?

Cheers

all it takes is a generous smear around the cap.
You don't need to take the plug out, all it takes is, um, a generous smear around the cap, as per the instructions here (http://forums.sv650.org/showpost.php?p=1076369&postcount=6).

[northwind]

Aye, you goop the seal rather than the plug itself, so teh plug can stay where it is- just pull the lead from the head, and then splatch some grease onto the round rubber seal that you'll find. You might be able to get a good result just by clearing the drain hole and fiddling with the seal, but tbh I reckon, why bother when there's a definate fix that's easier...

Both splatch and goop are technical terms, you understand :cool:

[markmoto]

front plug like to sieze in the cylinderhead aswell so abit of copper slip on the sparkplug threads is good insurance against this.

[drefraser]

I rode my '99 SV yesterday and definitely lost a cylinder for most of the sodden journey. But now that I know the fix for the bike who's got the cure for wet crotch syndrome? Goretex my ****.

Don't get so excited by the vibrations :-$

[drefraser]

I was sort of hoping that silicone grease might help both areas ...

[Draper]

where is this so-called 'plug hole cover'?

Definite +1 to that

[JamesMio]

Dammit Dammit Dammit!!!!!

Went for a quick warm up (read as get drenched in the freezing rain) before the local Toy Run this afternoon, bike kept cutting out and running on a fraction of it's normal power... Sounds very much like the Water In Plug syndrome and a large kick up the a$$ for not sorting this out sooner!!!

Ordering the Silicon Gloop from Maplins right this very minute!!!

[peahead]

so i take the spark plug cap off and put it inside the hole where the plug sits or cover the rubber cap then put it back in?

cheers:D

What Northy said. :D

[alan pasfield]

i used a wee bit of wd40 and that worked for me

[ejohnh]

I doubt if a wee bit of WD40 would last thru 9 days of torrential rain thru France and Spain :o)... The silicon grease did the job for me ..

[dyzio]

WD-40 is a fix.
To cure the problem use silicone grease and fender extenda as said before.

[ejohnh]

I got 2 fender extenders festering in my garage still. Could find nothing(adhesive) to fix either one securely, without having to use screws, so I resorted to the goop. I should have done that in the first place.
