As the proud new owner of a 2009 C-14 with 5500 miles, what are some of the things that I should be extra careful with and check before the warranty is up in 20 days? I smell a faint odor of antifreeze when it warms up, and it makes a rod bearing rattle for 2 seconds when started cold in the morning- are these normal to the bike or should I panic? Also, is it necessary that I buy 90 octane fuel or can I get by with 87? What oil brand, weight and filter should I use? Thanks for any advice for this new Connie owner.
