hissing noise when i try and start

[ash8865]

suzuki gsf 600 1997. there is a hissing noise when i try and start. what could be the problem?? iv done a full oil and filter change and also plugs can anyone help

[the grim reaper]

loads more detail needed. Is the engine turning over at all? Is the hissing more like a clicking noise? First instinct says flat battery but without further detail it's impossible to say.

Cheers

Grim

If all you get is a hiss, with no starter motor noise or engine rotation, then it's either an electrical short, or far more likely a completely dead battery.

Have you knocked the carbs or airfilter off when swapping the plugs? did you go in from the front or under the tank?

And finally are you sure all the plugs are 'home'??
