Hi folks. New to this forum and have some questions on motorcycle oils. I've revently purchased a 1999 Kawasaki Nomad 1500 which only has about 6000 miles on it. It has been sitting idle since 2002. I've had the carb pulled and cleaned at the dealer but I'm having a slight problem with some knocking in the top end. I used the Mobil 1 Red cap on my last bike until I heard they changed their formulation and added friction modifiers. There seem to be some dispute as to whether or not the new 'Gold' cap has replaced the 'Red' cap. Some say 'yes' and on another forum, a member spoke to a "technition' at Mobil and was told that they have added Moly to the Gold Cap formulation and would be bad for our wet clutch. Some are doubtful because this point of view is coming from a Mobil Person. would appreciate any views out there.
