FZR 250 floods and cuts out when taking off?

You really need a parts manual for it, or else just pull the tank off and have a look.

Let someone else comment also. I don't know that bike exactly.

Mmm... that's also another problem, the FZR 250 was never imported outside of Japan we only have Grey imports so there's no English manual for them.

Closest thing to it is a FZR 400 manual so Ive been told.

Could try cleaning the carby, it might be sticking, dirty and grotty if its that old.

When was its last service? I'd have thought they'd do that when they service them.

Very unlikely unless there is a pre-existing fault when it goes in for the service.....
However, you are right. The Carbs may not have been pulled apart for 20 years.... Most likely full of cr@p anyway. The fuel leaves behind a certain amount of scale when it evaporates off, and there isn't many places for it to go. Sometimes it can become as hard as gum (from a tree) to remove.


Take them apart and clean them out... If not too sure about that, then get the shop to do it.

Also ensure the Spark plugs are in good nick.
I have had a brand new one actually fail on me. It can happen.

If its not the exup exhaust valve, it'll be the carbs - to get these looked at (and dont expect them to be fixed first time, there are lots of things that could be wrong with carbs and you never know) cleaned and balanced - i'd say about $200 from a good shop.

yeah, or $500 from a bad 1, i had a problem simillar to this and it turned out a previous owner had removed the air fillter and stuffed a rag in the air box got the carbs cleaned and thats how much they charged, 3 days later was sitting at the lights and my foot was getting hot, looked down and the water pipe was pissing coolent all over my leg where they left a bolt loose, needless to say I dont use this shop anymore

Ok heres my theory. Can anyone else pick this apart please.

It's unlikely to be an internal engine or carburation fault, as its equal across all cylinders.

It might be a stuck float - carb drain or flush will fix?

If its flooding this badly, theres got to be a hole in a diaphragm somewhere - thats about the only way it can get that much fuel down itself.

Thanks for all the helps guys, Ill try taking it to a shop and maybe get a quote on it or atleast see what they think

I also didnt think it would be any major engine trouble as once the bike is running it goes hard, doesnt seem to have any problems when you give it shit.
