Monsoon strange effect approved!

check if the air breather hole in the cap is blocked. If not that , possibly some water is getting in the carb , maybe its trickling down from somewhere which makes it stop again and again.

Thanks Niks, I will check that. the air hole on the cap looks like the culprit. I can think of the low pressure inside the tank if the air hole is blocked with water. But I thought that wouldn't sufficient to to cut the fuel supply!

If the airhole is the problem, will installing the a plastic cover (the ones the come with a zip around the fuel cap) solve it? I am not a fan of them because the keep the moisture intact and the cap gets rusted much quicker than otherwise.

@ Niks :- I too face the similar issue. I have installed a K&N and had got it cleaned and reoiled just before the rains. One more thing, what is the effect of water entering the carb, i mean what are the damages expected to be caussed due to this.

@Rockrider - You nailed the issue, but to explain how it chokes the fuel, pls read my post here - http://www.xbhp.com/talkies/453197-post.html

Never even attempt to do this!!!

@argee: I did think about this possibility. Buy it did not convince me.

Its been a while since I have read the thermodynamics equations but just did not seem to fit. The amount of fuel that the bike may spend for say 5kms is rougly 100 ml. For an already -in reserve- vehicle 100 ml of less air (mind you there is no vaccum in the tank) create as much lower pressure that the fuel doesnt flow. Well I might be grossly out on estimates... so please feel free to correct me.

In the end.. what is the alternative? Cant live with it..

care to explain

The plastic cover blocks the air passages and even the drain passage.Plus the cover traps moisture on the fuel lid which lead to its rusting

@Rockrider - Do this experiment, open up the fuel lid & ride, I know its not safe, may be you can cover using a cloth strapped with a rubber band or so & this issue will never crop up.

Next time the motorcycle strands, just put your ears closely to the fuel lid cover & you can hear a mild hissing sound of the air being sucked in. If you hear this, then my theory works, if not let me know the outcome.

@argee. Err.. Thanks but I dont want to dry clean my trouser while on the run. More often than not, my tank is full enough to make a spill. However, I will make the observation you mentioned in the later half.

It never happened in the past 5 yrs.. so its quite likely that the water only may not be the culprit. There might dust particles etc.. If I cant figure a way to clean it, I'll change it.

**niks_devil666** · 07-13-2010, 03:07 PM

easiest way is to buy a new bike :P

**aargee** · 07-13-2010, 06:41 PM

Ok, if you're so skeptical, have a litre of petrol always in hand & run the motorcycle just few mm before reserve. You'll never encounter motorcycle stranding. Experiment this for a week or so.

@Aargee as I mentioned earlier, it happens mostly when its is raining or the bike was standing in the rain for sometime. So that rules out any possibility of experimenting with the cap open. I get the point you are attempting to convey. Thank you. with the cause established, can you suggest a solution?

@Pavan: Thanks.. I was not very inclined in having the cover.

@Niks:I wonder if there is anything else to it other than changing the bike (however tempting the suggestion might be

.)

I was hoping I'd get some time to visit a mech to see what he'd say.. If there he can clean it (for any blocking other than water) it would be good.. or I am looking for changing the cap.

What are the possibilities? Do I have to replace the cop with the old design, that comes with old gen bikes or can I have a new design (do you call it air cap or something?)
