just wondered if anyone would be kind enough to detail the procedure entailed to succesfully dewater a 4 stroke . Any hints/tips/warnings or general advice would be great. I want to know the definitive method before it happens to me when miles from anywhere and possibly alone!I'd also like to ask about the technique that was mentioned in the latest newsletter where water was expelled out of the inlet valves/carb/airbox rather than having to remove the tank etc to get to the plug. It may be obvious but how can you easily tell when the inlet valves are fully open? without dismantling anything?
2 Don't try to start it until you have got the water out.
3 Carry the tools you need to take out the spark plug and remove the air filter and drain the carb.
4 If you are lucky all you will need to do is to remove and dry (wring and shake) the air filter, and drain the float bowl to get any drops of water from the carburettor.
5 Tip up onto the back wheel to pour out water from the exhaust if it went under, it is worth tilting then returning to upright and repeating until no more comes out
6 If water got into the engine you may find the motor will not turn over because it is hydraulically locked so remove the spark plug then invert the bike by standing it on the seat and handlebars then turn the engine over until it stops spitting spray out.
7 Replace spark plug and start the bike, then replace the air filter, it may be harder to start with a damp filter and it will splutter until it dries.
8 Change the oil at the next opportunity because it will emulsify
9 Don't think that your mobile phone and AA card will suffice if you can't be bothered to carry tools, even if you can get a signal, and are somewhere the AA can reach/find you, you will be waiting longer than it takes to rectify and still have to do it later.
thanks guys ..still intrigued by the method where you drain it out of the inlet valves and how to know when they're fully open. I think It was mentioned by MR Squibb ?
