Dodgy Fuel Filter / Pump ?

The road leading to the little 'superette' where I occasionally buy a
sandwich, has an utterly _shite_ surface. So you can imagine the fun
today, when, every time I went over a bump, the bike 'lurched', as if the
throttle had been brutally (no other word for it) shut.

It _only_ (or almost only) happens when the bike goes over an uneven
surface, and if I then clutch and try to rev the engine, I can whack the
right hand full open, and the engine refuses to go over 2000 rpm.
Occasionally, I can 'cure' it by, if I find a sufficiently straight piece
of road, I cut the engine and restart it.

I'd plump for fuel filter, as I did run out of petrol that time, and it
more or less started around then. It might also be wishful thinking, as
when they replaced the fuel filter in the South of France, I was physically
present in the workshop, and so I know how to remove the tank etc. Also, a
fuel filter is (IIRC) 20¤, whereas a pump is a hell of a lot dearer.

Any ideas what it could be ? Could it be the fuel pump ? Could it be
electrical ? Do I buy a filter and whip off the tank this weekend ?

I'd replace the filter

8.50 GBP from motobins so the 20 euros is a bit high

By the way you don't need to remove the fuel tank you remove the tank
cap and the filter (and pump) live inside the tank. Best done when
you're lowish on fuel. Even better if you have a mate who's a
gynaecologist who will help out. )

PS although it sounds a bit more of an electrical issue rather than a
filter ....

Buy an 'onda. YKIMS

My money on a toss up between a dodgy electrical connection[1] or shite in
the fuel getting disturbed in the tank over rough roads and clogging up the
tank filter.

no carbs ... it's injectors on a K series

Yes, does to me too.

There was a problem with the earlier OE filters, but the symptoms
sound very different and I'd doubt that there are any of that type of
filter about nowadays anyway.
