I changed my end can on my 765R a few months back and have noticed a weird noise ever since. I followed the installation instructions and am confident no mistakes have been made.
The noise is a weird whine, a bit like someone gently sucking their teeth. It comes from the engine, maybe behind the radiator. It happens after the fuel pump finishes priming when switching on. If I switch off it carries on for t or so seconds before stopping. If I start the bike and ride then when I stop, sometimes it has stopped and sometimes it carries on until I turn the key off.
Anyone experienced this?
