New to the forum, and new to the F150, but not new to the questions above. I ride and have sold MC's for quite some time. Sold many a big bore custom, usually 113's and up and I've had a 98ci for over 7 years. I run a full syn, and converted most bikes over to them when possible. Big thing about a syn is they run MUCH lower temps which is quite important when it comes to an air cooled twin. But keep in mind that once you change over, you DON'T change back.

Of course i use the motorcraft filter, stay away from the ****ty frams!!!

It would not be the first time I was wrong about something! But from the certified MC mechs i worked with in the past I was told that is not something you want to do.

Switching from synthetic back to dino oil used to be a problem in the early days of synthetics but is no longer a problem. I believe the early synthetics would shrink/swell gaskets and seals, and switching back to dino oil would shrink them and cause leaking. The new synthetic oils no longer have this characteristic. It would be especially confusing these days with all the different types of synthetic oils, synthetic blends, etc.

Spend some time on bobistheoilguy.com if you want to live the "motor oil lifestyle" and research the switching issues, but my own policy is to use a good syn blend like Motorcraft or if I can get full synthetic oil for a great sale price, I'll use that. And I'm not worried about switching back to syn blend, say, from a modern full synthetic.
