Hypothetical question. Would a Fazer 600 run without its fuel pump as the tank is above carb height.
-
theoretically yes
but only if you go easy with the throttle.
The FZS400 has no pump.

Thanks bbrown1664. The float bowls are small without much volume once the floats are in. Suppose its good that these are one of the last engines to run without sillybollocks unnecessary emissions regulations gubbins. It seems a few other newer engines have increased in capacity to achieve similar power to what they had previously before being strangled. Where's the sense in that? Then again, I have been called a stupid ignoramus ludite before.

Interesting question. I have wondered in the past if the pump packed in when on a foreign tour, if I could carry on. (95% of the things I worry about never happen. The other 5% was a puncture, twice!). I think as long as the pump is removed from the system it would be o.k., but as BBROWN implies the fuel flow might not be up to using full power and maybe a danger of running weak. I would think the pump would have to be bye passed because of the one way valves in it. There are plenty of bikes with similar carbs that don't have a fuel pump. Maybe the pump is only there as a safety feature rather than the vacuum operated tap set up that is on some bikes. Just my thoughts.

I have thoughts too limax2 which usualy isn't a good idea. Never crossed my mind about the safety aspect, told you my thoughts aren't the best😀

Yep the fuel pump would have to be removed.
A couple of problems can occur so it's not advised over a long term.
The fuel pump also acts as a fuel cut off when the ignition is off. If you've got a sticky float valve in a carb you could end up with all your petrol leaking onto the floor.
Fuel starvation at high revs.

Ta Hugh Mungus, I've no intention of removing items, curiosity that's all. 👍

It's good to know that if it packs up 200 miles from home you're not completely up the creek with no paddle.
Whether the pipe would reach the carbs or how you join the two bits of pipe together by the side of the road is another problem but if you can get to a garage/DIY store it could be done cheaply. Probably less hassle than calling a breakdown service.

Seat off then easy enough to tip the tank back after front bolt removal
