Gpz500 engine help

[Joe Marcon]

Just bought a quadzilla 200 with a kawazaki 500 gpz engine in. And the left hand cylinder (sitting on bike) has stopped . I started it up didnt hold idle so knew it dropped a cylinder saw fuel leaking from the cylinder, either from exhaust studs or somewhere else :S, if the coil pack has packed im would this make the cylinder leak fuel as its not sparking it? Or is it something else . Only just got it and its been gay lol :(. I thought it was carbs,
But its not

Could the fuel line have come off? I wouldn't have a clue tbh, that's why I ask org too

[mikerj]

How do you know it's not a carb problem? Have you actually checked for a spark?

[Biker Biggles]

If petrol is pouring out of the cylinder I would think its a carb problem.Probably a stuck or sunk float or a crudded up valve allowing fuel to flow constantly from the tank into the carb,then flooding into the engine,then coming out somewhere.

[Joe Marcon]

Well im going to test ht lead against engine for spark. I do think its the carbs now lol . New carbs or??

[Joe Marcon]

Haha . Gunna check and stick a fuel filter on

Dont blame the poor old gpz engine. My old k reg commuter hack starts first time, pulls well and has never dropped to one cylinder! Sounds like float sticking/crud under needle. Have you been out in wet(i know its hard to avoid) or off road? Wondered if it had got moisture to it, I have heard gpz were prone to it though mine hasn't.

Haha i been on fields and thats it . Gunna get new spark plugs . And coil packs .
