Pollution problems or coincidence?

Hi everyone,
Any british riders experienced any starting, running problems with their xs400 over the last few days?
My bike ran fine last week but had trouble starting it yesterday, once I got it running throttle bogged down as if running on partially blocked jets Pulled the carbs, blew the jets and put them back on.
Same problem.
Feels like fuel starvation.
Just wondered if it's linked to the pollution problem at the moment!

I'd say if you can breathe, the bike can breathe..

unless you're running without any air filter and actual gunk got into the carbs

have you checked your fuel tank for contents ?

and how about your inline fuel filter, is that still flowing well? I've had mine clog up a few times due to fine rust particles from my tank

Thanks Willem.
Fuel flowed through as usual when I primed it earlier, half a tank of fuel.
Just took off the pod filters, bike started easier but still bogging down.
I then opened the garage door and the bike died when it breathed the atmosphere!
I try opening the idle mixture screws half a turn and see what that does!

The media over here is reporting that the London Fog over there is presently full of dust from the Sahara desert.
Typical modern media sensationalism?
If real, could the microns on the dust be small enough to get through filter paper?

it's as bad here as it is over in london but there's no 'smog alert' announced. There is one in belgium and in the UK, we just have the same smog but a higher level of what we call harmful or something. Your bike should be fine I think, but I'll check mine in a few minutes when I get home and report back

nope mine runs just fine, no change whatsoever

I have a DOHC (Seca model) with stock airfilter but I doubt it makes a difference

Thanks For that Willem and thanks Lou.
Looks like it's tinkering time again then!
