Carb kit GSF250 - And other problems

[nzlsaf]

Hi All,

New here so not sure if this is the right section, Im sure mods will move this if not.

I'm after a carb kit for my suzuki bandit GSF250, its a 1995 model and the carb for cylinder 1 is leaking into the cylinder and out of the overflow. Does anyone have any suggestions other than Coleman Suzuki (who i will try tomoro).

Also i am having problems starting the bike, im thinking flooding a cylinder isnt helping things but any other suggestions, i may be after a coilpack as well, it seems to be getting spark but in touching the leads no1 is also shorting out.

Thanks in advance

Umm, you are the weakest link, goodby. All in good fun though.

Stuck float needle, or incorrect float height, or even a bung float needle (which is my pick if it's happening all of a sudden).

Every 250 bandit I've ever had anything to do with (I didn't touch it honest) seem to be finicky starter uppers. Yes - fuel taps, valve clearances, plugs, coils, ignition all have to be bang on or there is a lot of whirring and not much riding. Nice bikes though.

A stuck vaccum valve.

Try turning the fuel tap off when it's not being used. Untill the actual issue is fixed ... it should help.

whutt if it's a vacuum tap and doesn't have a off?
but yes, sounds like the prime (if it has it) could be putting gas thru ahead of the carbs.. not so good. if you never use it then blocking it off would be a quik fux.

what esacerly are you gonna do with a carb kit anyhow??

if it's leaking overflow on one carb then strip it down, soak it in petrol/ carb cleaner, blow out the airwaves, set the floats a half mil down, check the float-valve, blow e'erything out with air. re-fit. if still have problems then post again.

"in touching the leads it seems to be shorting out" - run it in a dark garage and any short will be very obvious. i doubt it's a coil problem, HT lead if anythang but i doubt it...

What he said.
I might have a needle/valve that fits, but I won't be home for a week. Can check then if you haven't got a kit.
It's quite common for them to do this, bloody annoying little things.

My Bandit was like that. Would have major starting issues unless I turned the fuel tap off when not in use.

I've always thought the Bandit 250 was the nicest of the inline learner bikes. They are just sounding like heaps of shit now.

If it's just a bit of crud in the bottom of the carb ... with the motor off, open the drain plug on the carb (usually can done with a flat screwdriver) and drain the carb. It shoul take less than a minute to drain ... so if it continues to flow it will be the the vaccum vale that "needs work". If it does shut off ... turn the tap to prime and let it flow for a few seconds more. Usually helps if can catch the fuel you drain out to see if anything was in the carb.

before you type-think

i have struck a number of bikes in my time where the vaccuum take off for the fuel tap is on #1 cylinder,thereby drawing too much fuel into the cylinder via a malfunctioning fuel diapragm

Shit no, the entertainment of my posts is how often I say something stupid.

I read your post to mean the tap wasn't turning off, rather than the diaphragm was the source of the extra fuel.

My '92 Bandit 250 is a mint little runner. When I first bought it it was a sack of shit due to carbie issues, running way too rich, flooding and difficult to start - I had to lean it way out just to make it run OK.

Then came the discovery that the original needles and needle jets the Mikunis came fitted with were made of some kind of alloy of cream cheese and papier mache. Replaced those and it runs perfectly, super reliable. Apparently it was a common issue on Mikuni'ed Suzukis in the early 90s, the original part numbers got superseded pretty quickly.

Just do a carbie clean/balance/mixture adjust about every 4-6 months and it's good as gold.

Emulsion tubes wear out of round too.
