I started having the misfiring, running on one cylinder when damp/wet a few months back. I found the fix on this site, can't find it again to say thank you!!

 

So the definative fix :-

Get a mountain bike inner tube cut two six inch lengths from it. Put the coil inside the inner tube, it is a tight fit.

Use self amalgamating tape to seal the ends.

Since doing this I have ridden through some really foul weather up and down the M1 and the TDM never misses a beat.

 

I was worried about over heating, but as it has been at least three months, in all temperatures so I guess this is not an issue.

I hope this helps someone else.

 

The blame is really with Yamaha - crap coils.

It has been nearly six months since I wrapped the coils in the MTB tubes.

During this time I have ridden through some of the worst rain storms for hundreds of years, or so they say on the news!!

The TDM has never missed a beat, nor has there been an issue with coils overheating.

wrapping your coils in rubber is definately the way to go.

Hi Guys

 Have done the air box mod today and would have waterproofed the HT leads but a cant get my hands in behind the rad to pull the lead of the plug. Anyone come up with an idea to get the leads of the plugs yet for us big handed people.

 

Cheers

Get hold of plug cap, place a bit of card or rubber on top of cam cover as cushion and use it as a pivot point to pull plug cap up. Simples.

A bit late for a reply but I had this very same issue. Sometimes in light rain and not when riding through flood waters up to the axle - and sometimes when thundering down.

 

The problem comes from one of the connections that lives behind the airbox under the tank.  I had used liquid electrica tape to seal up everything with the coils and added extra heat shrink over the leads.  I was cleaning the area under the rear of the tank one day and it wouldn't start for the same problem.  WD40 in the (2 or 3) plugs fixed it right up and it hasn't done it since.  Has since sealed them up with liquid electrical tape as well :)

I know this thread is 3 years old now but I've been experiencing the same problem for the first time in the bikes 21 years. 

Go out in the rain and it drops to one cylinder, with mine it seems only under load, back the throttle off and she comes back to life, no good when you're overtaking though.

I found after replacing both coils and cleaning every electrical connection I could find that it was arcing out between the HT lead, where it goes into the plug cap, and the engine casing. I followed the self amalgamating tape suggestion and it has partly fixed the problem. Last weekend, in the rain going to the Dragon rally, it started to do it again, I can't see any obvious arcing out so I'm running out of ideas. 

I've looked on Fowlers website for new plug caps and the buggers are £45 each ! yikes !

Correct fix... REPLACE LEADS with quality items. You can then wrap if you feel the need.

I had the same problem and bought a length of good quality carbon core HT lead, wrapped it up well in self-amalgamating tape and haven't had a problem since. The only other thing I did made sure the leads were long enough to rest them in the side panels away from the frame.

I was looking up high quality high tension leads and generally they were copper. Years back I got advised to get carbon core, so did. It's been fine, but reading about it, in some leads the core disintegrates apparently.

Yes that's what happened to mine now you mention it, did'nt take long either, likely a bad quality me thinks as well.

Seem to recall it was a definite no no for the 9r but the reason alludes me now, maybe to do with spark plug caps or iridium sparkies !! but then your's are doing the job.

NGK SD05FM-R..Fitted these a long time back and never had a problem since...perfect sealing fit through the cam cover grommets too with a smear of Vaseline to assist..hth.
Promo says they're hard plastic. They're not, they're rubberised and semi flexible..
