    Is this oil good for a 08 RK I saw it on the oil thread, don't know what bike it was used in. SPECTRO 20/50 FULL SYN FOR MOTOR
    SPECTRO PRIMARY LUB ( DON'T HAVE A # )
    SPECTRO 75/140 GL5 FOR TRANNY
    I have always used syn 3 in motor/ belray for tranny and primary what ever HD put in.

    Everybody has their own preference as far as what's the best oil for their bike. It's kind of like asking what's your favorite restaurant :) There's lots of info and polls (stickys) here:

    Oil - Harley Davidson Community

    I use either Amsoil or Syn3.

    Thanks to many members in this Forum I switched to Spectro a few weeks ago. I know very little about oil but was told and read here that it by far one of the best oils. I have chosen same oils as you. And it was a huge task finding it on Montreal.

    I've been running Spectro in all three holes for years with very good results.
    Spectro semi-synthetic 20W50 for the engine.
    I do use the Spectro 6-speed oil for the tranny.
    Made for the Harley 6-speeds. I never had a noise problem (some do) before but it does help those that do have a noise problem.

    Air cooled engines are noisy by design. Some oils may help a bit but that would probably vary also from engine to engine too. Some say they hear more noise with an oil like Mobil 1 but I have not had that experience.

    Spectro full syn 20-50 in motor.
    Spectro 6 speed in tranny.
    HD formula + in primary.
    I've always used HD syn prior to this last change. I've done some research and it seems this Spectro oil is great so I decided to give it a try. However I can't really tell the difference except that it costs even more than Harley stuff. The bike still clacks real loud when shifting. I can get it locally so I'll continue to use it.
