Suzuki bandit 600 (1999) problem

Hello everyone,:winkie:

I have problems with my bandit 600. When its cold weather or it stand for few hours the bike starts very very hard and cutting off.
Also after few minutes of warming when i add throttle its just cutting off, so i need to ride with choke about 10 minutes. 

Recently i changed sparkplugs and engine oil.
Can this be problem with air filter? I also tried to start the bike without air filter, but nothing changed..
Also i can't set idle speed above 900rpm.
It was to the point where if I touched the throttle, the bike would bogg and stall. After about 10 mins though, the bike was running well enough to take for a ride.
Please help, i'm lost.

cutting off

Sounds like a carb issue (water in float bowls) also the pilots jets could be partly blocked,these jets controll mostly up to 2/3000 rpm.If the carb hasn`t been tampered you could also have a rusty tank letting crap through.

Has this bike been out off use for a time? 

Oh and welcome.

i love these guess the faults

this could be as simple as a badly adjusted choke cable, then carb balance then into them carbs as jaffa say's.........if your asking and not telling about your air filter (if its dirty its fecked) then i strongly suggest you take it to a mechanic................or just keep her running:wink:

Thanks for reply. Three days ago i cleaned my carbs (Before that, it also functioned poorly).

I didn't noticed any water in float bowls. But i have rust in my tank. Also i have oil in air cleaner drain hose..?
I think i'll just take it to mechanic or something.

Did you check if the pilot jets were clear?

Also if possible fit an inline filter between the tap and the carbs.

I suggest you have a compression test done on all 4 cylinders.

It sounds like your bike is running as lean as lean can be, and it's only when you've got enough heat into the engine that it can support the tiny amount of fuel getting through. As it's below 3500 it is still your pilot circuit that is at fault. If it's been stood for any time the fuel will have gone stale in a matter of weeks. You say you've inspected the pilot jets, but if the fuel is stale it will have coated the jets in shellac or varnish as it evaporated, so they look ok but the passages are squeezed. Poking wire down the hole is considered sacrilege, but sometimes needs must. What you could do to start with is set the pilot screws to the factory setting of 1.75 turns out, then turn them out half a turn at a time to see if that has a positive effect.

Let us know how you get on.....
