Hi All,

I found recently when I turn the key in the on position I can hear the fuel pump kick in as normal but I also hear a sucktion noise almost sounds like when you nip a garden hose.the bike starts perfect and runs perfect ... Any Ideas???

First of all, welcome to the forum. I'm not too tech savvy on the 1800, but on fuel injection there is usually a return line to the tank, you might be just hearing the fuel flowing through the system. If it runs correctly and doesn't have any leaks, I wouldn't be too concerned.

Welcome to the site Chuck. It's not something I notice on my 1800, but maybe your ears are a tad more sensitive than mine. There are a lot of vacuum hoses on a Wing and possibly one of them could be sucking air or making noise. But if that's the case there would likely be some type of stumble in the running of the bike.
