My 1984 K100 has become difficult to start. It fires straight away but doesn't catch but after a few attempts it will start on a part open throttle. It sounds when it "clears its throat" that it's been too rich but it runs well above 1500rpm. Below that it won't idle very well, cuts out momentarily and idle speed is up and down. On occasion the fuel pump starts whining. When this happens I switch off, leave it a few minutes and the pump is then usually quiet. I've replaced fuel and air filters, removed all the block connectors I can find under the tank and cleaned them, including the earth connectors and the connectors to the air flow meter and efi unit.
Is there anything else I should be looking at?
