Cutting out in the rain

<< < (2/3) > >>

matthewmosse:
Had a lot of this on both my 125's in the last 3 years, every time it was plug caps, though on the 500 the whole ht lead right back to the coil might be suspect due to age. I always found wd40 in the right place sorted it, though on the kh125 I sometimes needed to apply 2 or 3 times in 20 miles in extreme rain - a moto x plug cap in place of the old ngk thing sorted it. I added a small can of wd40 to the toolkit, lasts a very long time just used for this. After a while the residue seems to prevent re occorance of the problem if you are too lazy to replace the plug caps, spray grease might speed this up.

I wouldn't be without WD40 as a water dispersant. It works wonders.

This morning I've removed the leads, cleaned and inspected them. The connections look sound at both ends, no corrosion - copper still shiny.
I found two very slight marks on the insulation where the leads had been rubbing on the frame so I've covered every bit of lead that touches the frame or anything else with a bit of fuel hose for extra insulation.
The whole lot has then been drowned in WD40, and I've ordered two little 50ml tins to fit under the seat somewhere.

I also found that the points cover gasket was out of shape and not sealing in some areas so I've siliconed the lip on the cover, just waiting for it to dry before refitting as I don't want to glue it on.

Is there anything else that's worth doing?
I could replace the caps but they're only 2 years and 1500 miles old.

Green1:
I bet you sorted it if the points were getting wet that would definitely affect it.

My 550 does not like the rain either. Friend of mine swears by throwing a bucket of water over the engine, if it stops you know you have something to resolve.
