I am a complete and unapologetic newb when it comes to any sort of motor bike. I just picked up my used '05 Burgman 650 and I am still learning all of its features and maintenance issues. While checking the oil I found three tubes that just hang under the bike. Are they supposed to be attached to something? There are no obvious fittings that are missing tubes and I could find no mention in the owner’s manual. Any help here would be appreciated.
