Re: how do you clear a flooded engine?
turn the fuel off and give it half a dozen kicks,that should clear any petrol in the bore.
failing that a bbq lighter down the bore but stand back abit. if you rode it all day and now its not starting try a new plug first because its more than likely suffocated in oil,even after a good clean. and possibly you've worn your rings down if you only used cheap chinese ones? so that it wont have enough compression to fire off the kickstart,so new plug and try kicking it... if not try bump starting it,then report back.personally i wouldnt adjust the carb' as your previous settings are known to be working. |
Re: how do you clear a flooded engine?
Still not had it running yet.
Ive tried everything suggested other than the BBQ lighter. I think it may well be the spark, it seems ok testing it on the exhaust but as soon as i kick it over its wet through. Tried bump starting it and it almost feels like its going to fire but never does. The bike had just had a piston rebuild before i bought it, im not sure if its chinese but theres probably a good chance as ive seen kits on ebay for £45. If a new plug doesnt work do you think i should pressure test for compression? Any idea what it should be? |
Re: how do you clear a flooded engine?
Leaving the fuel tap on wouldn't flood the engine as the engine needs to turn over in order to suck fuel into the barrel but due to excessive kicking chances are its now flooded.
Ignition off Throttle wide open 10kicks Ignition on Choke on Of it starts turn the tickover up and let it idle for 5 mins |
Re: how do you clear a flooded engine?
I didnt check the wires upto the coil but the plug was sparking so these must be working atleast?
I took the plug and and kicked it over numerous times but no luck. Still gets wet and oily instantly. If the new plug doesnt help i will take a look at the piston and rings. If the rings were knackered would petrol be getting into the transmission oil? maybe worth draining that to see? It has had a top end rebuild recently, and i have the old piston which still looks in good condition. The lad started it up first kick before i bought the bike, but it did bog a little when i gave it a quick run, i assumed this was because of the rich running in oil ratio. I guess if none of this works i will need to remove the barrel and check the piston size against it? |
Re: how do you clear a flooded engine?
possibly your coil is breaking down under load.
also check to see if theres any water in your stator area. try a new plug then check its sparking correctly,then compression test etc' |
Re: how do you clear a flooded engine?
Cheers Harrison, massive help matey.
Ill try the new plug tonight and see how it goes. |

ie,the big end will have fuel in it. that is why its called flooding the enigne. if the tap is on,& the carb can overflow(transporting the bike in a van would do this),then the fuel will have got past your reedvalve & flooded into the big end. if you think this could be the case,there is an easy solution. you need to get the fuel out of there. if you remove the spark plug,then get one of our mated to help you stand the bike on its head. if you hold the front brake on & lift the back end in the air has high as you can,then push the kickstart a few times with your hand to turn the engine over. any fuel that is in the big end will spew out of the sparkplug hole. if no fuel comes out,then your bike is not flooded. |

I see what you mean about fuel flooding the engine when its been transported, but if theres fuel in the bottom end i think theres a problem with the piston itself. |
Re: how do you clear a flooded engine?
depends where abouts on the stroke the piston was when you turned the bike off last time.
