Excessive Moistness

seems to be the cause of the 750SS running badly below 3000rpm as the
rainy days this week have proved.
WD40 doesnt seem to help so is there a really effective waterproof but
electrically conductive spray out there? Putting in the garage until a
dry day comes along isnt a goer , as its my winter hack.....

I take it you meant _non_conductive spray? Try any silicone based product.
Even Mr Sheen works well, but make sure everything is dry before you use it
as you'll trap any moisture already present. I use silicone grease round the
HT coil/lead area and also where the rubber boot lives on the plug caps.
Have you got decent plug caps? I'd replace them with NGKs if not and also
the HT leads (if possible) in any case. Cheap insurance for reliable winter
riding.

Have you tried a new set of HT leads? Moisture is very good at finding weak
insulation.

 

ACF50

 

Odd. Mine's never missed a beat in any wet weather, despite nearly
submarining on occasion (the French Run back from Bayeux springs to
mind). As someone else said, replace HT leads. Well, try the plug caps
first as they're cheaper and easier to do.

 

Yep. Also, old coils tend to develop micro-cracks that let moisture seep in.
If that's your problem the simplest fix is to replace them, but some folks
have had success drying them in an oven, then coating them with a suitable
sealant.

 

Sucking his keyboard for inspiration, Howard typed:

Do you mean APF50? If so, it's brilliant on exposed metalwork and is
advertised as highly conductive, suitable for switches, so maybe not for HT
leads if you're looking to insulate something. I'm not sure how well it
would fare close to a cylinder head. If you get it on the exhausts, it
burns off like WD40, but takes ten times as long and smells fifty times as
bad. It's fine on the engine cases, though. Highly recommended for general
winterising.

ACF50. Self-immolates.

 

ACF 50.

Seconded. Old Italian HT components are not terribly competent when rain
tested. NGK caps and proper *wire* cored HT lead is the way to go. The
ones I put on the Morini twenty years ago are still OK (unlike one
twenty-seven year old transducer).

IIRC, yours was behaving itself, but Niall's was tending to misfire.

My Italian twin, OTOH, behaved impeccably.

 

Waxoyl's good for this, after you've changed the obvious suspects like
leads
and plug caps.

Spray it on when it's nice and dry though, or it'll just seal the damp
in.
