fuel issue

sometimes after about a week bike starts, coughs splutters and cuts out, after lifting tank and fiddling with pipes it starts and runs fine all day, have tried rerouting the level cable as I thought it might be trapping a pipe, can some one confirm if this is correct, under supply pipe, over breather and drain?



today it just coughs and splutters, cuts out when revved, even with the tank lifted so maybe something else, do you need to prime injectors?
only ever had carb bikes before so bit stuck

thanks

Check the vent hose at gas cap isn't pinched. I remember reading about that issue. Long shot but check it.

Looks like the tank water drain hose maybe slightly kinked (and poossibly more so wit tank down) which may cause a problem if left sitting for a while.

Don't need to prime injectors, but when you turn the ignition on you should give teh bike time to prime the fuel pump and run the STPs through their startup sequence, it only takes 2 seconds and you can hear it when it starts and also when its finished

You are not getting any FI lights or codes?

thanks will look at that, after a few hours of sitting it is now okay, did take the tank off and on, still wonder if I routed the Gauge lead correctly, think the connector could be pushing on a pipe

To check if it's the breather pipe next time it does it undo gas cap then try starting and see what happens.
It could also be a bit of water in the fuel tank so get some methylated spirits and put about 100ml in the tank.
Metho mixes with water and petrol so it basically breaks the water down.
