Hi everyone
Straight to the point last nite my divvy froze over really bad and in the morning wouldn't start!
battery is fine, starter is working great. It seems there is no fuel getting to the engine, I have checked the tank and the fuel filter and both have petrol going through them but thats as far as I have got!?
Thanks
Ian

Did you try it again this afternoon after it had thawed out?

sounds like frozen carbs....blanket over the tank will stop that freezing - also try a hair dryer if you realy want to thaw it out quickly - not too close mind!

Is it a 900 or 600??
....asking ther obvious but you have not ran out of petrol have you....?
turned the petrol to off in your frustration??
start at the begining and work your way from the tank to the carbs looking for the obvious...
eletrical problems maybe? Have you tried bump starting it?
so many questions I know....

And the tank has just gone into reserve, tried it in all 3 positions!
The battery and starter are running very strong!
And I havnt yet tried bumping!
Thanks

What if a lot of condensation has built up over time, and there is 3 litres of water in the bottom of the tank?
Then when you have gone onto reserve you have, technically run out of fuel because it's all water.
Drain the tank and start again with a fill of new petrol, and try again.

Wot he showaddydadito said.......plus have you tried all the obvious like WD40 in the side stand electrics, the kill switch, clutch electrics to name but a few areas where a fault may be.
It could be that you have developed a dreaded live wire off under the tank too....
a process of elimination me thinks.....

Thanks

Drain the carbs and dont forget to use the prime position on the fuel tap.
With that amount of water, there must a huge leak letting the rain in. Check under the tank for holes high up above the fuel level and check the filler cap is sealing properly. If the rim is rusty its probably not sealing.

The fuel cap seals had gone and I replaced the cap last week, so am guessing the previous owner didn't look at her much!!
How do I drain the carbs !?
Thanks
Ian

On the backs of the carbs, at the bottom on the float chamber cover, there's a small screw with a nipple under it, that's the drain screw. When you turn the screw a turn or two it lets the float chamber drain out the hole. Obviously you have to make sure the fuel supply isn't on prime when you're doing this or it'll keep getting refilled, and you'll need to put it on prime for a minute or two once you're done and have closed the drains to let the bowls refill before it'll start.

The screws are easily messed up. Use a SHARP wide & well-fitting screwdriver.

Got the bike going again so thanks for that everyone.
Couldn't drain one of the carbs tho cus the screw was already messed up! Will the water eventually pass through or will I have to drain it at some point!?

If it's running on all four cylinders, it's already passed through, so don't worry about it.
Try putting some IPA (isopropyl alcohol) or Silkolene FST additive in the petrol - that "dissolves" the water and will get rid of any that remains.
It will also help to stop the dreaded carb icing - which if you've never experienced it feels like the bike's cutting out after say a spell on the motorway - quite worrying until you know it's just a bit of water!

Yeah I used to get carb icing really badly on my old bandit 600. So yeah will give it a go, thanks.
Still have the prob of the bike ideling at like 2.5rpm when it warns up! Been told it mite be water getting in the manifolds but it dose it on the dryest of days!?

Been told it mite be water getting in the manifolds but it dose it on the dryest of days!? fuel tank off and dismantle the airfilter compartment - clean out ALL hoses (especially crank case to airbox - get rid of the white engine gunk) Fit a new airfilter and then make sure when you put the airfilter box back on, all 4 rubber oulets are clamped and tightened and seated properly. if it is still rising when warm it could be "setting the right fuel mixture and carb balancing time"....  |

A fast tickover on a warm engine usually means its running weak so check for air leaks behind the carbs or via the throttle spindles. But also check the choke mechanism is OK.

Thanks alot guys will give it good look over as soon as all this bad weather is out of the way and get back to you.

Well cleaned out the air filter and found alot of white crap in the pipes to the engine. Its made abit of a difference to the tick over but it still starts to climb slightly. So I have also adjusted the idle speed. So when warm atm it stays at about 1.3, but is still quite revvy unless this is normal!?

That sounds about right for a 600.

That sounds about right for a 600. +1 nb - a new airfilter makes the world of a difference too... |

+1 fairly normal, get 1050 cold - 1450 hot here

Post by CD on Feb 7, 2012 16:46:36 GMT
They will rev on choke but you can adjust the choke revs if its going too high.
If its revving for seemingly no reason you might have an air leak - weak mixture can cause a revvy tickover.

Post by bikerian123 on Feb 7, 2012 21:13:27 GMT
I have got the revs down to about 1000 when cold 1450 when hot. But when revving they take a while to go back down, and they are always going up and down slightly.
I have sprayed under the carbs while the engine is running and can't see any disturbance!
I know I have a slight leak in the exhaust system, and I have ordered I new air filter!

If the revs are going up and down it could well mean the carbs need balancing.

......But when revving they take a while to go back down, and they are always going up and down slightly....... When the bike is fully warmed up the revs do tend to "fluctuate" a little within about a 400 RPM window/area - any more and it might be carbs that need adjusting as bobh said...but pretty sure the air filter will help to cure it before you go down the road of carb balancing... |

Post by bikerian123 on Feb 12, 2012 19:26:59 GMT
Right I have fitted a new air filter and the revs are alot less erratic and a smoother throttle response!
So alot better just need to adjust the idle again. Have noticed a much stronger petrol smell from the exhaust!

Is a choke plunger sticking open?
