Posted: 13:40 - 14 May 2009 Post subject: bike won't start after heavy rain |
|
|
Couple of weeks ago i left my bike standing outside all night in the rain, uncovered. Went to start it up the next morning and wouldn't start! I could hear the ignition noise but the engine was reluctant to get going at all. After about 10 mins of trying it suddenly burst into life. Miracle? Has anyone else had the same problem? I generally don't make a habit of leaving my wheels in the rain but I was under the impression that a 'little' rain wouldn't hurt. How wrong was I... |

hmm i wouldn't say the rain was THAT bad the heavy rain i experienced is made to look like a mild drizzle compared to that! Hmm i know what you mean metalforever i get that occasionally ( i have a 10 year old er-5) but it did sound as if the underlying cause of the problem was to do with water; i believe the battery is okay because it usually starts first time without a problem if it has been a dry day and left outside. Possibly water in the fuel mixture?/ water interfering with the ignition spark? |

that does seem logical rob, thanks. I think i will make a habit of placing a cover over my bike if and when it rains as well as looking at the weather forecast, something i have never bothered to do |

Many bikes are renowned for this. Being more exposed than cars, the bike's electrics are prone to corrosion from damp. Some common places are the starter switch/killswitch, side stand switch, coils (on old bikes like mine the ignition coils apparently develop tiny cracks which only lets in water in mist or heavy rain), and the spark plug caps.
I'd say that, unless you have a single, the condition of the spark plug caps shouldn't stop the bike starting completely, rather just make it run like crap until the engine is warm and the water has evaporated.
My GPZ did exactly what you described in a heavy downpour. Wouldn't start for 5 or 10 minutes then suddenly it burst into life. A quick spray of WD40 round all the usual places made sure it didn't happen again. ____________________ H100 Breaking for spares |

There used to be a spray which formed a kind of plasticky seal over plugs/etc available from Halrfauds (Dampstart IIRC). Used it on an old Mini Cooper I used to have. Kept the moisture out instead of having to remove it when already in.

I remember that stuff, it was great, spray on and it dried to a semi flexible coating, too much if i remember and after a while it started to crack, still good stuff though.

indeed, when it gets wet, douse liberally in WD40 and all ye water based maladies should disappear!
Holts Damp Start Autoplast is the best for old electrics. Whilst the bike is dry, whip the tank off and give the electrics agood spray with contact cleaner to remove grease and crap, allow the spray to evaporate then spray liberally with the autoplast, this forms aplastic coating that keeps the damp up, great stuff!
Also give your coils and HT leads a coating. make sure the HT caps are ON the plugs then give them a dousing too. If you have the caps off you can get some inside and coat the contact thus preventing a spark |
