Bandit 600

Hi, my 10 yr old bandit is just out of winter storage, when i tried to start it it took ages. I changed the plugs to Iridium and it started, however I think its only firing on two cylinders and won't go over 5,500 revs. Any idea's. Is this a garage job or a home fix ? and how much am I looking at. Thanks.

I had this with my bandit never did figure it out, I would suggest switching the coils around and see if it fires on different cyclinders.

Is swapping the coils around a job for the DIY er or does it mean a trip to the garage ? Any one tried this at home ?

Id suggest draining the carbs and checking the petrol that comes out.

My bandit was left for a long time before i bought it and water had gotten into the tank.

The petrol could also have gummed up blocking/flooding the carbs. But drain them first and check for water.

From that diagram cylinders 1-4 are linked and 2-3 are linked if it is 1 and 4 or 2 and 3 not firering it's likely coils.

Ok guy's just checked the condition of the coil leads and spark of the plugs, all appear fine and are working, I know because I touched one by mistake. Anyway, the right hand side of the engine is not working, its not warming up and the plugs appear brand new, no carbon on them at all, so i am confident that it must be something else. Any idea's.

You state 3/4 aren't firing (right side) ... is there fuel getting through, i.e. are the plugs wet when you take them out?

Possibly carb floats are a little sticky ... using a screwdriver (handle end) give the carbs a couple of taps on the float bowls.

Thanks for thehelp guy's. I've tried the carbs and fuel appears to be getting through, I say this because I opened the drain screw slightly and fuel flows freely. When I start the bike, using the choke on full, the fuel ignites and the exhaust pops and bangs, as if to much fuel is getting through? I know it sounds a bit weird but Iam thinking a trip to the garage is in order. Could the cylinders be stuck ?

Not likely. Its most probably an issue with the fuel/air mixture. What was the condition of the fuel when you drained it into a glass?

Also, how is the exhaust smoke looking?

Fuel clear, initial burst of smoke(tiny amount) then that's also is clear. Although the smell of petrol is also present once bike is running.

Got the Haynes manual out. The carb section looks a bit tricky but will give it a try. Thanks for the help.

I would suggest blocked up carbs. If its been stored for a long time without petrol additives the carbs can easily get blocked with varnish and gum.

I cleaned mine a couple weeks back without much idea of what i was doing and went fine, so its definatley something to do yourself if your confident enough.

Garages will charge you £100+ easily.

If they are blocked though a firm tap on the bowls with a screwdriver may clear them. Drain them, flush them through on prime, and tap them.

Although, waiting to see if anyone comes along with other problems it could be, but carbs sounds like a dead ringer.

COMPLETELY drain ALL of the carburettors of ALL fuel. Then put the tap on prime and refill them. Will probably be ok then.

If then no joy, the carbs will have to come off for a clean, as stated previously.

Right Lads, Carbs off yesterday and cleaned all bar one bowl, coz i could nt get the screw out. One carb heater nipple snapped off, but i have glued it back on. The other three were nipping clean. Sprayed all jets through with carb Clean and replaced the system. primed them replaced the battery and tried to start it, took a while but it fired up, then stopped again. Tried to start it and the battery died. Am pig sick. Will post update tomorrow when battery charged. thanks again, will the carb warmer hold or should i replace it ?

Back again, bike started after a bit coughing and its ticking over nicely around 900 revs, however original problem still remains. The bike is still only firing n two cylinders. Anyone recommend a decent bike shop in the North East that won't take my eyes out ?

How about dropping a little bit of fuel straight down the plug ports, and trying to get the engine turned over that way, or am i creating a Suzuki bomb ?
